      Hi,

      We want to connect an arduino to the J10 UART.
      When we try voxl-uart-loopback -d 7, it fails.
      When we use 'voxl-i2c scan 7 400000`, it recognizes the device (besides the UART TX and RX we connected the SDA and SCL as well)

      We also tried it with a GPS, so that we could be sure it wasn't the arduino code, but it had the same result: uart failed and i2c was recognized.

      / # serial-read-teensy -d 7
      INITIALIZING
      Sending 10 bytes:
      0123456789
      Transfer should take ~1736us, sleeping for 6736us (+5000us overhead)
      Reading back data...
      ERROR: voxl_uart_read 0 bytes, expected 10
      closing uart bus
      FAIL
      

      Can you help us with this?

      Thanks in advance!

        @SHofmeester J10 on the VOXL2 is a SPI port. https://docs.modalai.com/voxl2-connectors/#j10---external-spi
