Dab tsi yog PSM (Txuag Lub Zog Txuag) hauv LTE Cat. M1?
Dab tsi yog PSM (Txuag Lub Zog Txuag) hauv LTE Cat. M1?

LTE Cat. M1 (Cat. M1) yog tus qauv los ntawm 3GPP uas yog Lub Koom Haum Txheej Txheem Txheej Txheem Thoob Ntiaj Teb thiab tau pab thoob tebchaws los ntawm SKT. Tsis tas li, Cat. M1 yog tus sawv cev LPWAN (Tsawg-Lub Hwjchim Loj-Cheeb Tsam Network) thev naus laus zis thiab tshwj xeeb hauv IoT daim ntawv thov kev txhim kho. Kev siv hluav taws xob ntawm cov cuab yeej siv roj teeb hauv IoT daim ntawv thov cuam tshuam ncaj qha rau lub cuab yeej lub neej voj voog, yog li txo qis kev siv lub zog yog qhov tseem ceeb heev. Vim li no, Cat. M1 txhawb PSM thiab Txhim Kho DRX (eDRX) thev naus laus zis, uas txo qis kev siv zog ntau. Nrog PSM, koj tuaj yeem txo qis kev siv hluav taws xob los ntawm kev teeb tsa lub zog ua haujlwm / pw tsaug zog ntawm lub cuab yeej.

Phau ntawv qhia no piav qhia yuav teeb tsa PSM cov haujlwm li cas siv Woori-net Cat. M1 module. Cat. M1 module feem ntau yog tswj los ntawm AT cov lus txib uas muaj los ntawm UART interface. PSM ua haujlwm kuj tseem tuaj yeem qhib / ua haujlwm siv AT hais kom ua.

2.1 Teeb WM-N400MSE module

Yog tias koj siv WM-N400MSE module, siv IoT Starter Kit thiab nws yuav tsum tau teeb tsa raws li hauv qab no:

2.2 Nruab UART DriverAfter teeb kho vajtse, Txuas ntawm lub rooj tsavxwm thiab PC siv micro USB txuas. PC kev ua haujlwm yuav lees paub qhov chaw nres nkoj COM txuas nrog lub cuab yeej. Yog tias lub cuab yeej txuas nrog kom raug, koj tuaj yeem tshawb xyuas ob lub chaw nres nkoj COM, thiab xa AT cov lus txib uas siv Standard COM Port. Windows Koj tuaj yeem tshawb xyuas qhov chaw nres nkoj COM hauv Device Manager hauv Control Panel.

Yog tias koj tsis tuaj yeem txheeb xyuas qhov chaw nres nkoj COM hauv Tus Thawj Tswj Ntaus Ntawv, rub tawm thiab teeb tsa tus tsav tsheb los ntawm qhov txuas hauv qab no. Link: CP210x USB rau UART Choj VCP Tsav Tsheb

3.1 AT+CPSMS

AT + CPSMS cov lus txib tau siv los siv PSM, thiab Lub voj voog nquag / pw tsaug zog tuaj yeem hloov kho los ntawm kev ntsuas ntsuas. Koj tuaj yeem hloov kho Lub Caij Nyoog / Pw tsaug zog los ntawm kev teeb tus nqi 4 thiab tus nqi 5 zaug ntawm qhov hais kom ua. Teeb 6-8 khoom los teeb tsa chav nyob ntawm lub sijhawm thiab 1-5 khoom los teeb tus nqi. Piv txwv, yog tias tus lej 4 tau teeb tsa rau 1010011, chav tsev yog 1 feeb txij li 6-8 khoom yog 101, yog li tus nqi yog 6 vim tias nws tau teeb tsa rau 1-2 ntsis, yog li nws tau teeb tsa rau 6 feeb.

3.2 AT $$ DBS

Thaum lub sijhawm teb ntawm AT $$ DBS cov lus txib, Lub Sijhawm Ua Haujlwm / Pw tsaug zog tuaj yeem suav nrog siv PSM-ACTIVE thiab PSM-PERIODIC qhov ntsuas qhov ntsuas.

3.3 AT*SKT*RESET

Yog tias koj siv cov lus txib AT saum toj no los siv PSM, koj yuav tsum rov pib dua kom txuag chaw.

Txhawm rau txiav txim siab lub ntsiab lus ntawm kev nkag mus rau Lub Xeev / pw tsaug zog lub xeev, AT cov lus txib yuav tsum tau xa ib ntus thiab lees paub. Nov yog qhov tshwm sim ntawm kev sim nrog PSM-ACTIVE teeb tsa rau 60 vib nas this thiab PSM-PERIODIC teeb tsa rau 180 vib nas this.

Qhov xwm txheej nquag / pw tsaug zog tuaj yeem txiav txim siab los ntawm LD3 ntawm IoT cov khoom siv pib. Yog tias LD3 teeb ntsuab, nws nyob hauv Lub Xeev Active. Yog tias nws tawm, nws nyob hauv lub xeev Sleep. Hauv qab no yog qhov tshwm sim ntawm kev sim nrog PSM-ACTIVE teeb tsa rau 60s thiab PSM-PERIODIC teeb tsa rau 180s. Cov khoom siv IoT oob khab tau cim tias yog Pib Pib thaum lub teeb qhib, thiab Kev Pib Poob tau qhia thaum lub teeb tawm.

Cov txiaj ntsig saum toj no qhia tias lub xeev ua haujlwm yog PSM-ACTIVE + 24-27 vib nas this, thiab lub xeev pw tsaug zog yog PSM-PERIODIC-PSM-ACTIVE + 3-4 vib nas this
