I have a nRF9160 Thing Plus (separately having trouble setting up the development environment per the Sparkfun tutorial, failing during “west update”.)

I really only want to use the 9160 as a modem, so I attempted to use pre-built images:

1) Installed the pre-built Bootloader (v2) from https://docs.jaredwolff.com/nrf9160-downloads.html with a Segger jlink. (since somewhere along the line, I over-wrote the factory install)
2) When I boot the device and connect Putty, I see the device boot and messages from the accelerometer.
3) Install the pre-built AT Client, https://docs.jaredwolff.com/files/at-client-v1.3.2.bin via:

newtmgr -c serial image upload at-client-v1.3.2.bin

4) Reset the board
5) Open LTE Link Monitor, following the settings guidance at: https://learn.sparkfun.com/tutorials/nrf9160-thing-plus-hookup-guide#example---at-client-sample. I am able to select the board in the pulldown.
6) All commands timeout
So:
2) suggests the board is functional.
3) was error free, so I assume the install was good

There are no LEDs lit and commands AT, AT+CFUN?, AT+CFUN=1 timeout.

Any suggestions on what I should try next ? Thx.

    I’ll add, if you connect to the device and hit the reset button do you see any output?

    flow control is off. (all settings are off)
    when I hit rst on board, I see nothing in the terminal

    I will add, when you load any app with newtmgr you either need to run the newtmgr -c serial reset command, hit the reset button or power cycle the board. I know you mentioned that earlier but just to make it clear for anyone else who may come across this.

    1) Goto bootloader mode (by MD/RST sequence)

    david Downloads $ newtmgr -c serial reset
Done
david Downloads $ newtmgr -c serial image upload v2-091821-1423-merged.hex
 0 B / 584.81 KiB [-----------------------------------------------------------------------------]   0.00%Error: NMP timeout
david Downloads $ newtmgr -c serial reset
Error: NMP timeout
david Downloads $

    2) Flashed using jlink
    3) Blue light flashes, LTE Link Monitor connects
    4) AT+CFUN? -> +CFUN: 0 crlf OK crlf

    Is this a later version of AT_CLIENT merged with bootloader?

      … sorry also, if I need this board as a modem for an ESP32 board (running Toit) … is there a description of the difference between “AT_Client” and “Serial LTE Modem”

      many thanks

        davidg238 Serial LTE Modem has some more features. It depends on what you need.

        For instance you can setup a MQTT connection using Serial LTE Modem.
