Dear Nordic developer community,
I am in the process of developing a communication with the PC via the USB CDC ACM interface of the nRF52840 chip. The information received from the PC will first be evaluated via this serial interface and then distributed via the BT Mesh. That is the plan. This plan is to be realized with the nRF52840 dongle, which will first be implemented and tested on the nRF52840 DK. The procedure for this is already available, has also been implemented and is running on the nRF52840 DK.
The main procedure initialise
- a few status LEDs
- and then the initialization of the serial interface,
- at the end Bluetooth is switched on and the mesh is initialized.
/** @file main.c
* @brief This is a special BT Mesh Node that acts as the bridge between a computer and the BT Mesh.
*
* As platform should be used Nordic's nRF52840 Dongle. The platform has its own USB Device as well as a BT Stack.

* 2. enable USB subsystem [usb_enable()] and associated hardware ( if the underlying platform supports that, e.g. nRF52832 don't supports that )

After the build process for the nRF52840 DK (no warnings, no errors) and the subsequent flashing, everything works perfectly. The serial interface shows me all log and output data and the processed data is sent to the mesh.
When I create a build for the dongle, the serial interface and the RGB LED on the system work, but only up to the point at which I want to initialise the BT Mesh. At this point, the system hangs and does not continue. The terminal can no longer connect to the serial interface and the RGB LED no longer changes its status.
I have already looked at the complete generated .configs of both system builds, but have not really found the decisive clue as to why it runs on the DK system and on the dongle only when either the serial interface or Bluetooth is switched off.
It would be great if you could take a look at the generated configs or use your wealth of experience to give me a tip as to why the USB / Mesh combination does not work on the dongle.
For a better overview, I have compared the two generated configuration files and copied all the differences to the top (after this line --- everthing is equal). This way you can see the different configuration attributes at a glance when comparing them in an editor; the generated configs are quite long. Hope that helps.
And of course, I can share the complete project, but I think it's a bit too much for now.
Thanks in advance for any help
best regards
uli
