nrf mesh for thingy53

[William.wei]

hi support team,

i want running chat demo in mesh fold in ncs2.9.0, but it doesn't support thingy53 natively. so i ported some of the file from light to chat demo. you can see it in attachment, however it doesn't work normal. could someone help to see why it is not working?

5775.chat.7z

and here is my provision process.

however,when i build nrf5340dk/nrf5340/cpuapp/ns, it is working, this configuration is also copied from light/boards.

Regards,

William.

Hello,

Have you tried doing what it said at the very end of your video? Is the device still present in the network (if you connect via another node)?

The fact that it doesn't work on the thingy, but works on the DK makes me suspect that it is the lacking programmer/UART translator that causes some issues. You could try to copy the two files thingy53_nrf5340_cpuapp.conf and thingy53_nrf5340_cpuapp.overlay from the sample: NCS\nrf\samples\bluetooth\peripheral_uart\boards into the chat\boards folder, and see if that helps. If not, we would need to look at the logs from the application. Do you have a debugger that you can use to debug the Thingy53?

Best regards,

Edvin

thanks edvin,

you gave me a good advice on this, because it is usb shell, thingy53 need to wait for usb ready and then, i can privision this node, so either i need to use putty and make usb ready, or delete usb detect function.

thingy53_nrf5340_cpuapp.conf2870.thingy53_nrf5340_cpuapp.overlay

so i set CONFIG_SHELL_BACKEND_SERIAL_CHECK_DTR=n in prj.conf and it works now.

really thanks for your advice.

Regards,

William.
