Hello everyone.
I made a custom PCB based on arduino nano 33 iot, and added a few sensors.
The steps I did were:
- I burnt the bootloader into the ATSAMD21G18A. Tested the blink and it was ok.
- Updated the latest firmware into NINA module (V1.5.0);
- Tested the CheckFirmwareVersion example from WIFININA library.
The output was ok: "Passed" - After this tested the ScanNetworks example, and the output is:
Scanning available networks...
** Scan Networks **
number of available networks: 0
After not understanding what was going on, i programmed the ATSAMD21G18A with the SerialNINAPassthrough, and programmed the ESP32 of NINA with the scanNetworks code from the arduino-esp32 library.
Found out that the NINA module was scanning networks correctly (working standalone), however, for some reason it is not communicating with ATSAMD21G18A.
After this I tested the bluetooth. With the SerialNINAPassthrough on the ATSAMD21G18A , programmed the NINA with the Serial2SerialBT. Bluetooth was working fine.
After all this testing looks like the problem might be with the SPI communication between NINA and the ATSAMD21G18A. I attached the schematics. At this point I dont understand if this is a HW or SW problem.
