nrf9151 UDP DATA Transmission

[Jostin]

Hi everyone,

I am currently working with the nRF9151DK using nRF Connect SDK v3.2.3 (Zephyr OS v4.2.99). I am trying to run a basic UDP sample with a Terrestar Solutions SIM card, but I am unable to get a network attachment or an IP address and then unable to send data.

Here is my current setup:

Board: nRF9151DK

Modem Firmware: mfw_nrf91x1_2.0.4

APN: data.mono (configured via CONFIG_PDN_DEFAULT_APN)

System Mode: Tested both LTE-M (Mode 1) and NB-IoT (Mode 2)

Thanks in advance for your help!

Best regards,

[Jostin]

Hello,

I confirm that the SIM card worked well when using AT Commands

Now, I am using nrf_modem_at_printf to send AT commands directly from the application and it's working perfectly.

Best regards,
