BG96 cellular connection issue. #218

Closed adityathakekar closed 3 years ago

adityathakekar commented 3 years ago

changed the uart pins and edited the json as per the documentation. complete link to the previous issue can be found here.

https://github.com/ARMmbed/mbed-os-example-cellular/issues/217#issue-824624940

  1. Cellular nb iot sim cannot connect to the network.
  2. we can connect to the nb-iot sim via arduino.

Do we need AT commands in the code? Or we just need to edit the json?

Hey, i am using up to date clone of repository and the code does not work ,connecting to bg96 cellular nb iot using udp. Changed the uart pins to D1 and D0.

Apologies for the bots, they can't be reasoned with.

I don't have your board unfortunately so you'll have to help me out a bit. Can you please enable traces, set them to debug level and share the log?

You can also try turning on AT prints with cellular.debug-at.

adityathakekar commented 3 years ago

Modem power on Connecting to cellular context in 0ms

and the timer continues. There is no connection with cellular network. cellular.debug.at = true

paul-szczepanek-arm commented 3 years ago

I'd expect a bit more prints if you had tracing on.

Doesn't look like your modem ever powers on.

Are you sure you're using the latest cellular example? Please clone this repo, git checkout development, mbed deploy. Change the mbed_app.json options for tracing to true, set trace level to debug, enable at traces. Compile and flash. Connect serial and dump it into a file, attach the file with the log to the issue together with your json.

Here's a normal log:

I imagine the reason the modem doesn't power on is because there is no communication across the AT protocol. Check the correct pins are configured in the json.

Attaching the logs with json file .. using Dragion NB-iot shield quectel BG96

OK, looks like you don't have communicatin between the board and the shield. I think you need to configure the QUECTEL_BG96. Look in https://github.com/ARMmbed/mbed-os/blob/master/connectivity/drivers/cellular/QUECTEL/BG96/mbed_lib.json for values you need to provide.

This doesn't look like an issue with the example though. I recommend the forums or if there's something wrong with BG96 the mbed-os repo.

@paul-szczepanek-arm thanks for your time. closing this issue.
