Hi,

Can we use SIM other than iBasis to use nrf cloud?

My SIM does not have a PUK. How to proceed without entering it.

We need SIM too kit document for nrf9161.

We are using nrf9161 developemnt board with BLE to test our GPS. How to get the Command list /protocol for this device?

Hello,

Using UART (RXD/TXD) between two IC's is a good solution solution, also include the hardware flow control signals (RTS/CTS), this allow low power operation when there is no data either way (using LPUART driver). Personally I recommend that you have all control over BLE fully handled in the nRF54L15, and you make your own UART commands between the nRF9161 and nRF54L15 that contain the application data you want to send. This will limit the amount of data you need to send over UART, which will lower the power consumption and make it easier to develop code and have a clean cut between the nRF54L15 (BLE) and nRF9161 (Cellular).

You will need to have two SWD interfaces here, one for the nRF54L15 and one for the nRF9161.
