LTE Connection Timeout Error (-116)

[GUOQI123]

Use nrf_modem_lib_init() to initialize the modem, followed by lte_lc_connect() to connect to LTE. However, it consistently fails to connect to LTE. After it times out, the serial log displays:

This issue has only started occurring in the past two days. There haven’t been any significant changes to the program, and even minor changes did not involve the modem-related code.

I’m quite confused about the cause of this issue and hope you can provide some guidance.

Thank you for your help,
Guo Qi

Hello, 

What version of the nRF Connect SDK are you building your application with? And what modem FW is your nRF9151 running? Could you also plese provide full log from your device? Is this a custom board or a nRF9151DK?

thanks

Kind regards,
Øyvind

Apologies for not describing the issue clearly earlier, and sorry for any confusion caused.

The development kit I’m using is the Nordic nRF9151DK, and the SDK version is v2.7.0. However, I just discovered today that the device can now connect to LTE normally. This makes me suspect that the issue might have been related to the communication base station in my area.
