Topic: Problem with SAMD21 and WiFi NINA on custom board (Read 491 times) previous topic - next topic


Hello everybody,

I made an IoT sensor with MKR WiFi 1010, Shield SD and various i2c sensors.

I made a special sketch and everything works perfectly.

Then, I created a custom board to incorporate everything, following exactly all the MKR, Shield and sensor circuit diagrams.

I programmed the bootloader on the SAMD21 chip and loaded the firmware of the NINA WiFi chip successfully.

With this new board, NINA WiFi does not work properly.

I can read MAC Address and Firmware Version but it seems that the RF part does not work.
I tried to launch a scan network but found no network.

I checked all board connections and they are correct ...

Someone who has had the same problem or can have a solution?

Thanks to those who will be able to help me.
