Connecting issues again

Connectivity
1

I finally got my final hardware solution for my project a Radxa X4. It has an Intel N100 and a RP2040 on the board.

I have ported over my code and am having issues getting real dash to connect to the com port.

I dumped out a sample of the data stream and cannot see an issue. Hoping that someone can catch what I’m missing, here is a picture of the data stream that I logged and displayed in a hex editer:

I can see the 4 byte header 44, 33, 22, 11 followed by 4 bytes of frame ids 81 0C 00 00, 82 0C 00 00, etc, along with each frames 8 byes of data.

Why doesn’t RealDash recognize this? I have the baud rate set properly.

thanks

Data looks good, so there must be a connection issue. Try different connection method/adapter.

The rp2040 and N100 are integrated on the same motherboard.

I connected to the com port with putty to capture the log, so it is hard to think there is a wiring issue.

Is there a way to read the file I capture into realdash to get a better understand on what is going wrong?

Make it read the file and think it is a serial connection?

5

Turning on RTS/CTS makes it work.

thanks for verifying the data looked good.
