Adding PPP to Zephyr mqtt_azure example

[JPSvanderWalt]

Hi, I want to add PPP protocol to the Zephyr mqtt_azure example.  I am using an nRF52840-DK with a Quectel BG-96 Modem.  The generic Zephyr gsm_modem example using PPP is working.  I am wondering how to add the PPP protocol to zephyr projects?  Is it as simple as adding an overlay to include PPP or do I have to put in more work?  I can not find Zephyr examples that include PPP except for the generic gsm_modem example.  Any guidance or help would be appreciated.

Hi,

 

NCS does not have support for this specific sample. I would recommend that you contact the zephyr community if there's something that is lacking or the sample does not work as intended.

The documentation for this sample can be found in the zephyr docs: https://docs.zephyrproject.org/latest/samples/net/gsm_modem/README.html

 The sample itself is tested with the "reel_board" board, which is based on a nRF52840, and uses UART as a communication protocol between the modem and the nRF. Other nRF52840 boards should be possible to port/configure to be used with the project, but might require additional settings.

Please note that the sample hasn't been tested with the specific modem that you're using, so no guarantees that it will work out-of-the-box. You can see the configuration for the sample in the prj.conf.

 

Kind regards,
