Kauj Ruam 14: Yuav Siv GSM Module Nrog PPPd (Raspberry Pi)

A) Ua ntej, hloov /boot/overlays/sc16is752-i2c.dtbo thiab xyuas kom tseeb tias I2C ua haujlwm tau zoo.

• Hloov sc16is752-i2c.dtbo
• Kev teeb tsa I2C

B) Nkag mus hais kom ua i2cset -y 1 0x16 0x23 0x40 kom rov pib dua GPRS module.

Tom qab khiav cov lus txib, koj yuav tsum tau tos me ntsis, txog 10 vib nas this

Koj kuj tseem tuaj yeem siv cov hauv qab no los pib dua.

Kauj Ruam 15: Yuav Ua Li Cas Txheeb Kuv Li GSM Module (Raspberry Pi)

Cov cai hauv qab no tau pom zoo kom ua tiav siv Python 3 thiab teeb tsa lub tsev qiv ntawv smbus:

ntshuam lub sijhawm tseem ceeb ntshuam smbus ntshuam tus neeg teb xov tooj ntshuam os

print ("Tos rau initializing …")

npav = smbus. SMBus (1)

bus.write_byte_data (0x16, 0x23, 0x40)

ser = serial. Serial ('/dev/ttySC0', 115200)

yog ser.isOpen == Cuav:

ser.open () sim: print ('-'*60) print ("Initializing A9G GPRS module.") print ("GSM connecting …") time.sleep (3) i = 0 while True: ser.write (str.encode ("AT+CCID / r")) size = ser.inWaiting () yog qhov loj! = 0: zuam = time.time () teb = ser.read (loj) ccid = str (teb, encoding = "utf -8 ") print (ccid) else: i = i + 1 ser.flushInput () time.sleep (1) tsuas yog KeyboardInterrupt: ser.close ()

Exec Test Script, raws li cov txiaj ntsig ntawm kev siv, peb tuaj yeem kuaj mob GSM module. Piv txwv li, rov qab los tom qab no, CME ERROR 53 yuam kev qhia rau peb lub zog tsis zoo. CME Code = GSM Cov khoom siv cuam tshuam txog qhov ua yuam kev

Tau kawg, tsab ntawv kuj tseem muaj qhov rov ua haujlwm. Yog tias koj tuaj yeem tso saib CCID kom raug, rov pib dua yog ua tiav.

Kauj Ruam 16: Yuav Siv Lora TX & RX Nrog C (Raspberry Pi)

Cov cai hauv qab no tau pom zoo kom ua tiav siv Python 3 thiab teeb tsa lub tsev qiv ntawv smbus.

Nws yuav tsum tau hloov pauv ntawm ob qhov IOT Node (A). Cov ntsiab lus xa los ntawm nws tus kheej tsis tuaj yeem txais los ntawm nws tus kheej. Thov khaws nws ua cov ntawv py rau kev ua tiav.

Yuav Xa Li Cas: Tom qab sau cov ntaub ntawv rau npe 0x01 - 0x10, teeb tsa L_TX ntsis kom pib xa cov ntaub ntawv.

ntshuam sij hawm ntshuam smbus ntshuam os ntshuam sys

Yuav Txais Txais Li Cas: Txheeb L_RXNE me ntsis, Yog tias teeb tsa, cov ntaub ntawv tshiab tuaj txog, tus chij no yuav tsum ua kom pom tseeb

ntshuam sij hawm ntshuam smbus ntshuam os ntshuam sys

npav = smbus. SMBus (1)

cov_data =

sim:

if bus.read_byte_data (0x16, 0x23) & 0x02: # manually clear L_RXNE bus.write_byte_data (0x16, 0x23, 0x00) register_list = [0x11, 0x12, 0x13, 0x14] # nyeem tawm cov ntaub ntawv rau qhov ntsuas hauv ntau (0x11, len (register_list) + 0x11): recv_data.append (bus.read_byte_data (0x16, register_list [index - 0x11]))

print ("Tau txais cov ntaub ntawv:")

print (recv_data) lwm yam: luam tawm ("Tsis tau txais cov ntaub ntawv tseem tsis tau ~") tshwj tsis yog KeyboardInterrupt: sys.exit ()

Kauj Ruam 17: Cov Lus Qhia Tshwj Xeeb ntawm I2C Bandwidth

Qhov txwv ntawm I2C nrawm yog 400kHz, vim yog I2C raws tu qauv, yog li cov cuab yeej siv tau zoo bandwidth qis dua 320kbps, ntau lub cuab yeej siv tau zoo bandwidth qis dua 160kbps. Kev txwv ntawm I2C UART Choj nrawm yog 115200bps. Thaum GPS thiab GSM ua haujlwm tib lub sijhawm, I2C bandwidth tsis txaus, vim tias 115.2kbps * 2 = 230.4kbps, yog li qee cov ntaub ntawv yuav dhau mus. Ru txo tus nqi baud ntawm GPS thiab GSM kev sib txuas lus tuaj yeem txhim kho kev sib txuas lus tsis txaus. Packing lwm DockerPi modules yuav siv ntxiv I2C bandwidth. At feem ntau, cov ntaub ntawv network nrawm yog qeeb, yog li GSM bandwidth tsis puv, yog li tsis muaj teeb meem hla dhau.
