Hi Dejan Simonovic,

"<inf> main: RSP : +CEREG: 0,2, ..." this log means you are not registered into network, please insert good SIM, that has good network coverage around your place.

Thanks,

Hi Dvl,

With the latest version of your project (for any SIM) there seems to be no registration to the network. With the previous iteration of your project, I was able to get "+CEREG: 0,1, ..." similar to what you showed in your previous log.

Best regards,
Dejan

Hi Dejan Simonovic,

will you please do power cycle of DK and flash same version code again and check if it might work.!!

I have Just tested following latest code and its working CoAPAndTCPServer_v0.1.zip. 

 

Thanks,

Hi Dvl,

I have tested again with your latest code. Pressing Reset button on the nrf9160-dk board does not change the output for me. In other words, it is "+CEREG: 0,2, ...". However, when I power cycle the nrf9160-dk board I get ZEPHYR FATAL ERROR shown below.


Using adddr2line on the faulting address

ncs\toolchains\cf2149caf2\opt\zephyr-sdk\arm-zephyr-eabi\bin> arm-zephyr-eabi-addr2line.exe -e <path_to_your_project>\build\zephyr\zephyr.elf 0x0001de7e

gives the following output

C:/Users/desi/ncs/v2.6.0/zephyr/lib/libc/newlib/libc-hooks.c:469

Can you replicate this on your nrf9160-dk when you power off/on the device?

Can you provide information how it works in your case? Is it working as expected or still gives "<err> main: error: accept: 23, -1"?

Hi Dejan Simonovic,

1. Working means SIM registrations is working. but i am still getting following error "<err> main: error: accept: 23, -1" .

2. Will you please provide me the APN of your SIM ? or just replace apn string (apn.static.bell) with your SIM apn in code. i have shared you, updated version v0.2 below. and then try, it might worked now !!

CoAPAndTCPServer_v0.2.zip

3. Please share log of AT+CGDCONT? FYI, I have added it, in v0.2 for debug purpose, it will now log every 1 second with network status read command. 

Thanks,

Dvl
