BG96 modem.waitForNetwork() always end up in 0,3 (Registration denied)

schmidie commented 3 years ago

Hi I have problems to get the TinyGSM running on my board. With this AT commands I can establish successfully a connection:

// Band Configuration
// 1NCE: 80 for Band 8
bg96_at("AT+QCFG=\"band\",0,0,80,1", 500);

// Configure RAT(s) to be Searched
// 0 Automatic, 1 Take effect immediately
bg96_at("AT+QCFG=\"nwscanmode\",0,1", 500);

// Configure RAT Searching Sequence
// (LTE Cat NB1 -> LTE Cat M1 -> GSM)
bg96_at("AT+QCFG=\"nwscanseq\",030201,1",500); 

// Configure Network Category to be Searched under 
// 0 LTE Cat M1,1 LTE Cat NB1,2 LTE Cat M1 and Cat NB1
bg96_at("AT+QCFG=\"iotopmode\",1,1",500);

// use PS domain service for data-service
// see http://prog3.com/sbdm/blog/dailinqing1984/article/details/45744565
bg96_at("AT+QCFG=\"servicedomain\",1,1", 500);

// Configure Parameters of a TCP/IP Context 
// <context_type>,<APN>,<username>,<password>,<authentication>
bg96_at("AT+QICSGP=1,1,\"iot.1nce.net\",\"\",\"\",1", 500); 

// Operator Selection
bg96_at("AT+COPS=0,0,\"26201\",9",500);

bg96_at("AT+COPS?",500);

// Query Network Information
bg96_at("AT+QNWINFO",300);

// Query and Report Signal Strength
bg96_at("AT+QCSQ",500);

// Signal Quality Report
bg96_at("AT+CSQ",500);

...but I would prefere to use TinyGSM ;-)

What are you working with?

Modem: Quectel BG96 Revision: BG96MAR02A07M1G Main processor board: nrf52840 (https://docs.rakwireless.com/Product-Categories/WisTrio/RAK5010-M/Overview/) TinyGSM version: 0.10.8 Code: WebClient example

Scenario, steps to reproduce

Hi, I try to get the TinyGSM running on my board but I always end up in AT+CREG => 0,3 => Registration denied. I just configured the tinyGSM like explained in the instructions. I set the APN (iot.1nce.net) and also tried to call modem.gprsConnect(apn, gprsUser, gprsPass); before network-search. I also tried completly erase the chip and flashed new bootloader.

Expected result

modem.waitForNetwork() => true

Actual result

AT+QIACT=1 ERROR

+CREG: 0,2 OK

+CREG: 0,3 OK

than it stays in +CREG: 0,3

Debug and AT command log

Wait...
bg96 power up!

Anyone has any idea ?

If your operator requires the band and technology to be set, you'll have to use some AT commands yourself. If you want to stick to TinyGSM, you can try something like: (Note: The GF() is just an abstraction for flash strings.)

// Band Configuration
// 1NCE: 80 for Band 8
modem.sendAT(GF("+QCFG=\"band\",0,0,80,1"));
modem.waitResponse(500);

// Configure RAT(s) to be Searched
// 0 Automatic, 1 Take effect immediately
modem.sendAT(GF("+QCFG=\"nwscanmode\",0,1"));
modem.waitResponse(500);

// Configure RAT Searching Sequence
// (LTE Cat NB1 -> LTE Cat M1 -> GSM)
modem.sendAT(GF("+QCFG=\"nwscanseq\",030201,1"));
modem.waitResponse(500);

// Configure Network Category to be Searched under 
// 0 LTE Cat M1,1 LTE Cat NB1,2 LTE Cat M1 and Cat NB1
modem.sendAT(GF("+QCFG=\"iotopmode\",1,1"));
modem.waitResponse(500);

// use PS domain service for data-service
// see http://prog3.com/sbdm/blog/dailinqing1984/article/details/45744565
modem.sendAT(GF("+QCFG=\"servicedomain\",1,1"));
modem.waitResponse(500);

// Configure Parameters of a TCP/IP Context 
// <context_type>,<APN>,<username>,<password>,<authentication>
modem.gprsConnect("iot.1nce.net");

:+1: cool, thanks! works good with

  modem.gprsConnect(apn, gprsUser, gprsPass);

  // Band Configuration
  // 1NCE: 80 for Band 8
  modem.sendAT(GF("+QCFG=\"band\",0,0,80,1"));
  modem.waitResponse(300);

  // Configure RAT(s) to be Searched
  // 0 Automatic, 1 Take effect immediately
  modem.sendAT(GF("+QCFG=\"nwscanmode\",0,1"));
  modem.waitResponse(300);

  // Configure RAT Searching Sequence
  // (LTE Cat NB1 -> LTE Cat M1 -> GSM)
  modem.sendAT(GF("+QCFG=\"nwscanseq\",030201,1"));
  modem.waitResponse(300);

  // Configure Network Category to be Searched under 
  // 0 LTE Cat M1,1 LTE Cat NB1,2 LTE Cat M1 and Cat NB1
  modem.sendAT(GF("+QCFG=\"iotopmode\",1,1"));
  modem.waitResponse(300);

  // Operator Selection
  modem.sendAT(GF("+COPS=1,2,\"26201\",9"));
  modem.waitResponse(300);
