Qhov tseeb, txhua qhov kev nthuav qhia cov yeeb yaj kiab ntawm koob hmoovTags thov lub luag haujlwm tseem ceeb thiab ntawm cov yam ntxwv tshwj xeeb sib txawv (zoo li Gadgets) tau ua nrog kev txhawb nqa ntawm Windows 10 Kev Hloov Kho Ib Hlis.

Kauj Ruam 3: Windows 10 - Cov Tsim Kho Tshiab - Version 1703

Tus Tsim Tsim Hloov Kho Windows 10 yog qhov ua haujlwm tsis zoo tshaj plaws (OS) los ntawm qhov pom ntawm Bluetooth Tsawg Zog li.

Yuav luag tsis muaj dab tsi ua haujlwm. Microsoft lees paub tias Kev Tsim Kho Hloov Tshiab tsoo Bluetooth Tsawg Zog (siv 1 thiab siv 2). Microsoft lub tuam txhab tau cog lus tias yuav kho kom sai li sai tau. Tab sis txij thaum ntawd los lawv tau tshaj tawm qhov hloov tshiab ntawm Windows (Caij Nplooj Ntoos Zeeg Hloov Kho Tshiab) thiab tsis muaj dab tsi tshwm sim - txog tam sim no nyob rau hauv Windows 10 Cov Tsim Tsim Hloov Kho tshiab, Bluetooth Tsawg Zog tseem tsis ua haujlwm.

Muaj ntau tus lej tshaj tawm ntawm cov rooj sib tham uas cov neeg sib txawv yws yws txog ntau yam ntawm Bluetooth cov cuab yeej uas tsis ua haujlwm tom qab hloov kho rau Cov Tsim Kho Tshiab (saib ntawm no, saib ntawm no, saib ntawm no, saib ntawm no thiab lwm yam).

Cov txiaj ntsig, kuv yuav qhia tam sim, tau txais tom qab ntau qhov kev sim: (1) ntawm lub desktop PC uas muaj CSR4.0 Bluetooth USB dongle (CSR8510 A10) thiab (2) ntawm Dell Inspiron P66F laptop nrog ua ke Bluetooth LE ntaus ntawv. Kuv paub muaj ntau txoj kev daws teeb meem hauv is taws nem txhawm rau kho ntau hom teeb meem Bluetooth. Kuv tau sim yuav luag txhua, tab sis tsis muaj dab tsi ua haujlwm (hloov kho tus tsav tsheb Bluetooth, khiav Windows daws teeb meem, xiam oob khab thiab qhib kev pabcuam cuam tshuam nrog Bluetooth thiab lwm yam)

Yog li, cia nthuav qhia cov txiaj ntsig:

1. CC2650STK:

a Ntawm lub khoos phis tawj version 1.40 ua ke SensorTag lub cuab yeej nrog Windows yog qhov ua tsis tau (Kuv rov ua cov txheej txheem ntau zaus, tsawg kawg 8-10 zaug, Kuv qhib thiab tua Bluetooth thiab kuv tau sim dua-cov txiaj ntsig zoo ib yam: nws ua tsis tau ntxiv cov cuab yeej no).

b. Ntawm lub khoos phis tawj version 1.20, PC pom lub SensorTag thiab kuv muaj peev xwm ua khub SensorTag nrog lub PC.

Tsis tas li, kuv muaj peev xwm tau txais Cov Ntaub Ntawv Nkag Mus Los. Tab sis, ntawm Qhov Tau Txais Cov Ntaub Ntawv Qhia Kev Pabcuam, los ntawm 9 tus yam ntxwv tsuas yog 6 tau teb thiab tsuas yog los ntawm lawv nws thiaj tuaj yeem tau txais cov ntaub ntawv.

Hloov chaw, Kuv tsis tuaj yeem teeb tsa lub cuab yeej thiab kuv tsis tuaj yeem khaws cov ntaub ntawv los ntawm cov cim los ntawm kev nyeem cov txheej txheem lossis los ntawm kev ceeb toom.

2. Thunderboard React:

Cov txheej txheem ua haujlwm muaj tus cwj pwm coj txawv txawv thaum pib txheej txheem kev sib koom. Hauv cov npe ntawm cov cuab yeej tshawb pom, SensorTag tshwm sim thiab ploj mus (nrog rau lub sijhawm 1… 1.5 s). Thaum kawg, thaum tus nas nyem ua tiav ntawm SensorTag, cov txheej txheem ua ke ua tiav thiab cov LEDs ntawm Thunderboard React (xiav thiab ntsuab ntsuab) muaj lub sijhawm thaum lawv ua haujlwm sib txuas ua ke nyob rau hauv hom atypical.

Kev nyeem ntawm cov yam ntxwv ntawm Kev Pabcuam Nkag Mus Rau Hauv (0x1800) tuaj yeem ua tiav yam tsis muaj teeb meem, tab sis kev nyeem los ntawm Cov Ntaub Ntawv Qhia Txog Kev Pabcuam (0x180A) tsis ua tiav ntawm tag nrho plaub yam ntxwv uas twb muaj lawm.

Teeb tsa lub cim (kos rau ntawm SensorTag), hom kev tau txais cov ntaub ntawv (ntawm Thunderboard React koj tsuas muaj peev xwm ua tau hauv qab no: (1) kom tau txais cov ntaub ntawv los ntawm kev ceeb toom los ntawm 3 lub ntsuas pa thiab (2) nyeem cov ntaub ntawv los ntawm lwm plaub lub ntsuas pa) yog tsis yooj yim sua. Yog li, qhov ua tsis tau ntawm kev tau txais cov ntaub ntawv tiag tiag los ntawm cov txiaj ntsig tau ncaj qha los ntawm no.

3. Thunderboard Sense:

Tib txoj kev sib dhos, pom rau Thunderboard React, tau pom tias tseem muaj nyob rau Thunderboard Sense - thaum peb xav ua kom tiav cov txheej txheem ua khub. Tab sis ntawm no, txhua yam tseem phem dua: tom qab kev sib koom ua ke, qhov kev thov koob hmoovTag tsis tuaj yeem txheeb xyuas SensorTag. Yog li, tsis muaj lub cuab yeej siv - tsis muaj qhov chaw los ntawm qhov chaw thov foom koob hmoov rau kom tau txais cov ntaub ntawv.

4. CC2541DK:

Tus cwj pwm zoo ib yam nrog tus cwj pwm CC2650STK (firmware version 1.40). Ntawm txhua qhov kev sim txuas, koj yuav tau txais cov lus yuam kev hauv qab no: "Sim txuas koj lub cuab yeej dua".

Yog li, hauv qhov xaus, tsis pub dhau qhov hloov tshiab ntawm Windows 10 (Tus Tsim Tsim Hloov Tshiab), nws tsis tuaj yeem sib txuas lus nrog ib ntawm plaub yam ntawm SensorTags taw qhia saum toj no. Thiaj li, kuv hais (ib zaug ntxiv) tias ntawm no kuv tau siv tib software version uas kuv kuj tau siv hauv txhua qhov kev sim ua Windows 10 Kev Hloov Kho Ib Hlis.

Kauj Ruam 4: Windows 10 - Caij Nplooj Ntoos Zeeg Tsim Kho Tshiab - Version 1709

Qhov no Windows 10 (1709 - OS Tsim 16299.19) yog cov kauj ruam loj heev rau tom ntej, piv nrog Windows 10 Cov Tsim Tsim Hloov Tshiab (nyob ntawm BLE yuav luag tsis muaj dab tsi ua haujlwm), tab sis tseem muaj txoj hauv kev ntev mus rau qib Windows 10 Kev Hloov Kho Ib Hlis (1607) kev ua haujlwm

Tab sis cia saib yog vim li cas kuv thiaj ua cov lus no:

1. CC2650STK (firmware version 1.40) & CC2541DK:

Kuv yuav kho ob lub cuab yeej ntawm no ib txhij vim tias lawv tus cwj pwm cuam tshuam nrog Windows 10 (1709) kev ua haujlwm zoo sib xws.

Kev sib koom ua ke thiab kev nyeem ntawv, los ntawm Kev Nkag Mus Rau Generic thiab Cov Kev Pabcuam Cov Ntaub Ntawv, ua haujlwm tau zoo yam tsis muaj teeb meem zoo li cas.

Cov teeb meem tsuas yog tshwm sim thaum peb xav nyeem cov ntaub ntawv los ntawm cov ntsuas. Cov txheej txheem xa cov ntaub ntawv los ntawm kev ceeb toom tsis ua haujlwm txhua.

Tib txoj hauv kev kom tau txais cov ntaub ntawv los ntawm cov ntsuas, kos rau hauv SensorTag, yog los ntawm kev siv lub tshuab nyeem ncaj qha los ntawm lub cuab yeej. Txoj hauv kev no muaj ob qhov teeb meem: (1) txo cov ntaub ntawv xa mus nrawm (raws li peb tau qhia saum toj no) thiab (2) yog tias txhua lub ntsuas ntsuas lees txais ib ntawm ob txoj hauv kev xa cov ntaub ntawv (los ntawm kev nyeem thiab ceeb toom), cov nyees khawm ntawm SensorTag tuaj yeem yog nug tsuas yog los ntawm cov txheej txheem ceeb toom. Ua tsaug rau qhov "tshwj xeeb" ntawm Windows 10 (1709) OS, kev thov koob hmoovTags thov siv, pib nrog version 9.7.8.0, txoj kev nyeem ntawv rau kev nrhiav cov ntaub ntawv ib yam nkaus.

Ib qho teeb meem tshwm sim nrog CC2650STK SensorTag muaj firmware version 1.20. Yog tias cov txheej txheem ntawm kev sib txuas thiab kev nyeem cov ntaub ntawv los ntawm Kev Pabcuam Nkag Mus Nkag tau ua haujlwm zoo heev, txheej txheem nyeem ntawv los ntawm Cov Ntaub Ntawv Xov Xwm pabcuam tsis tuaj yeem ua tau. Ib qho ntxiv, cov ntsuas nyeem ntawv (los ntawm SensorTag nrog lub khoos phis tawj no) tsis ua haujlwm los ntawm ib qho ntawm ob txoj hauv kev ua tau (nyeem lossis ceeb toom).

2. Thunderboard React:

Hauv tib hom zoo li Windows 10 Cov Tsim Tsim Hloov Tshiab, SensorTag tshwm sim thiab ploj thaum peb xav ntxiv Bluetooth ntaus ntawv tshiab. Tus cwj pwm zoo ib yam tuaj yeem hais txog hauv qhov chaw ua haujlwm ntawm Bluetooth lub khawm ua nrawm tau "Tsis txuas nrog" thiab "Thunderboard React" tau tshwm sim ntau zaus (thov saib hauv cov yeeb yaj kiab hauv qab no cov txheej txheem no pib los ntawm lub sijhawm ntsuas 5.14 s). Tam sim ntawd peb tuaj yeem xaus Thunderboard React tau ua txhaum, feem ntau yog los ntawm kev ua tsis raug ntawm kev tshaj tawm txoj haujlwm los ntawm Silicon Labs cov kws tsim khoom. Hloov tshiab - piv txwv li saib cov yeeb yaj kiab no hauv YouTube.

Tom qab ua ke ntawm SensorTag, daim ntawv thov foom koob hmoov tsis tuaj yeem pom Thunderboard React ntaus ntawv. Yog li, ntawm qhov no tsis muaj dab tsi ua haujlwm: Kev nkag mus tau yooj yim thiab Kev Pabcuam Cov Ntaub Ntawv lossis cov ntaub ntawv tau txais los ntawm cov ntsuas nkag hauv Thunderboard React SensorTag.

3. Thunderboard Sense:

Hom kev coj tus cwj pwm zoo ib yam li Thunderboard React. Cov cuab yeej Bluetooth no tau tshwm sim thiab ploj ntau zaus. Thaum cov txheej txheem ua ke ua tiav, nws muaj peev xwm nqa cov ntaub ntawv los ntawm Kev Pabcuam Nkag Mus Los. Tab sis los ntawm qhov no, tsis muaj dab tsi ua haujlwm ntxiv lawm.

Raws li qhov xaus, tam sim no ntawm Windows 10 Caij Nplooj Ntoos Zeeg Tsim Kho Tshiab (1709, tsim 16229.19) tsuas yog SensorTags tsim los ntawm TI (CC2650STK thiab CC2541DK) ua haujlwm. Ntau dua, lawv ua haujlwm nkaus xwb hauv hom nyeem ntawv. Tab sis mloog! Tsuas yog CC2650STK firmware version 1.40 yuav ua haujlwm hauv hom no. Hmoov tsis zoo, thaum koj yuav CC2650STK koj muaj lub sijhawm zoo heev ntawm kev siv lub cuab yeej nrog kho vajtse kho tshiab 1.20. Yog li, kom muaj peev xwm sib txuas lus nrog ib hom xws li SensorTag kev hloov kho nws yog qhov tsim nyog tsawg kawg rau qhov firmware version 1.40.

Koom nrog cov kauj ruam no, Kuv nthuav tawm cov yeeb yaj kiab uas ua pov thawj tag nrho cov lus tau hais saum toj no rau Windows 10 Cov Tsim Kev Hloov Pauv.

Txij li thawj zaug tso tawm Windows 10 Fall Creators Update (tsim 16229.19), thaum Lub Kaum Hli 17th, 2017, tsis muaj kev txhim kho lossis kho tsis raug cuam tshuam nrog Bluetooth LE txog KB4054517 (tso tawm rau lub Kaum Ob Hlis 12, 2017). Hauv KB4054517 (OS Tsim 16299.125) muaj qhov hloov pauv tseem ceeb ntawm Bluetooth LE (saib ntawm no): "Hais txog qhov teeb meem nrog tus kheej cov cuab yeej Bluetooth uas tsis txhawb kev sib koom". Txij li cov lus no tsis meej heev, Kuv tau txiav txim siab rov ua dua txhua qhov kev tshuaj xyuas uas kuv tau ua kom deb li deb thiab pom tias puas muaj kev txhim kho piv rau thawj zaug tso tawm Windows 10 Fall Creators Update (tsim 16229.19). … Thiab qhov xav tsis thoob me me, tam sim no kuv tuaj yeem tau txais: (1) cov ntaub ntawv los ntawm Thunderboard Sense (los ntawm cov cim kos rau ntawm SensorTag tab sis tsuas yog dhau los ntawm kev nyeem tshuab) thiab (2) txhua cov ntaub ntawv los ntawm Kev Siv Nkag Mus Los thiab Cov Khoom Siv Cov Ntaub Ntawv. Tsis muaj lwm yam kev txhim kho.

Kauj ruam 5: Windows 8

Raws li thawj Microsoft OS nrog BLE kev txhawb nqa, kev ua tiav yog qhov txaus siab, tab sis nws nyob deb dhau los ua qhov zoo tshaj plaws. Tsuas yog cov cuab yeej uas ua haujlwm nrog cov haujlwm no yog CC2650STK thiab CC2541DK.

Teeb lub sijhawm yuav khoom rau 150 [ms], rau CC2650STK, peb tuaj yeem tau txais cov ntaub ntawv (los ntawm txhua qhov kev ntsuas lub cim), ua raws li 150 [ms] tus nqi piv txwv, los ntawm cov txheej txheem ceeb toom yam tsis muaj teeb meem. Hmoov tsis zoo, siv CCC2650STK nyeem ntawv cov txheej txheem, peb tuaj yeem tau txais cov ntaub ntawv (los ntawm txhua lub ntsuas ntsuas) nrog lub sijhawm 2 vib nas this.

Qhov xwm txheej tau zuj zus thaum peb tham txog CC2541DK. Los ntawm kev ceeb toom cov txheej txheem, cov ntaub ntawv tau txais nrog lub sijhawm 0.4… 0.6 vib nas this. Thaum siv cov txheej txheem nyeem ntawv peb tuaj yeem khaws cov ntaub ntawv nrog lub sijhawm hloov pauv ntawm 2.8… 3 vib nas this. Cov xwm txheej zoo ib yam: lub sijhawm tau txais 150 [ms] los ntawm txhua lub ntsuas tau kos rau ntawm CC2541DK SensorTag.

Kauj ruam 6: Windows 7

Microsoft lub tuam txhab tau ntxiv kev txhawb nqa rau Bluetooth Tsawg Zog (BLE) pawg pib nrog Windows 8 kev ua haujlwm. Lawv tau muab API uas ua rau cov ntawv thov nkag mus rau BLE cov cuab yeej.

Tab sis Microsoft tsis tau xa BLE API's rau Windows 7. Lub Windows 7's built-in stack txhawb tsuas yog Bluetooth version 2.1/3.0, tsis muaj kev txhawb nqa rau BLE (4.0, 4.1 lossis 4.2). Yog li, los ntawm qhov pom ntawm tus tsim tawm nws tsis tuaj yeem sib txuas lus, hauv Windows 7, nrog BLE ntaus ntawv siv Windows 7's pawg.

TI lub tuam txhab muaj txoj haujlwm hu ua BLE Device Monitor uas muaj peev xwm: (1) khiav ntawm Windows 7 thiab (2) sib txuas lus nrog SensorTag. Tab sis koj yuav tsum siv rau qhov tshwj xeeb USB dongle (piv txwv li CC2540 Bluetooth Low Energy USB). Yog tias qhov chaws rau USB dongle tsis pub dawb, qhov chaws rau BLE Device Monitor tsis muaj - nws tsuas yog siv sab hauv ntawm TI tuam txhab.
