nRF5340 BLE mesh samples don't work properly

[RAlexeev]

I tried to launch your example "Bluetooth: Mesh Light" using nRF5340 PDK and I failed. I followed this guide developer.nordicsemi.com/.../README.html. Also I tried to launch an example "Bluetooth: Mesh" (docs.zephyrproject.org/.../README.html) using nRF5340 PDK and I failed. I wrote out all combinations of samples in a table below which I tried to build and run, but all of them didn't work properly. But when I built the sample "Bluetooth: Mesh Light" for nRF52840 DK, then everything worked properly. The problems occurred only in the case of nRF5340 PDK.

I used nRF Connect v3.4.1 Programmer to firmware a network core.

Explain to me, please, how to launch any sample of BLE mesh for nRF5340 PDK? Does the working sample exist at least?

Hi Roman, 

Please add the following code

    NRF_P0->PIN_CNF[0] = GPIO_PIN_CNF_MCUSEL_Peripheral << GPIO_PIN_CNF_MCUSEL_Pos;
    NRF_P0->PIN_CNF[1] = GPIO_PIN_CNF_MCUSEL_Peripheral << GPIO_PIN_CNF_MCUSEL_Pos;

Many thanks for your answer!

I followed your instruction and I managed to run a BLE mesh example on nRF5340 PDK. It was launched and I was able to connect to the node. Also, I provisioned and united nRF5340 PDK and nRF52840 DK in a single network using your nRF Mesh mobile app. I created groups there and added models of Generic On Off Servers from both boards. And when I connected to one board and changed states of groups then I faced a problem. There's a difference when I was connected to nRF52840 DK and nRF5340 PDK. In the case of connection to nRF52840 DK, I changed the state of a group and they changed for both boards. LEDs from both boards belonging to the single group turned on and turned off. But when I connected to nRF5340 PDK and did the same actions in groups, turning on and off LEDs, then only LEDs on nRF5340 PDK really changed, but LEDs on nRF52840 DK didn't change their states. It seems that nRF5340 PDK didn't retransmit packets or did it wrongly, or nRF52840 DK didn't recognize these retransmitted packets from nRF5340 PDK. Tell me, please, do you have the same problem, when you connect both nRF5340 PDK and nRF52840 DK in the single mesh network and you connect to nRF5340 PDK from nRF mesh mobile app and manage states of models from both boards in a group? In my case, LEDs on nRF52840 DK don't change their states, if I connect to nRF5340 PDK. But everything works if I connect and manage vice versa.

In addition, I also want to realize potential problems of connecting various devices to a single BLE mesh network, especially from various vendors. As I noticed, there's probably compatibility issue even between nRF5340 PDK and nRF52840 DK. Now I don't know for sure whether it's a compatibility problem or I did something wrongly, but I want to understand whether such a problem exists potentially or not.

Hi Romand, 

I'm testing the example and can reproduce the issue. I have reported to the developer, and he needs time to investigate this.
