RE: Switching from USB to UART

Hello,

I suspect that there is something in the way that you are trying to read the uart that strips away the '0's. 0 is a perfectly fine UART byte, and it shouldn't be cut out like this.

Using UART, you need to read out byte by byte, because there is no header or anything saying anything about the length of a message. It is being sent one byte at the time. You need to stitch the message back together in your application.

I suggest you have a look at the NCS\nrf\samples\bluetooth\peripheral_uart, and look at how this example reads the UART, and checks for special characters to determine whether to handle the message now, or wait for the next byte.

If that doesn't work out, is it possible for you to upload your project, so that I can replicate what you are seeing on a DK?

Best regards,

Edvin
