Not receiving whole hex array – serial communication

[Stig24]

There is probably an obvious reason for why I’m not receiving the whole hex array I sent?

Thanks

Hello,

Please try sizeof(tx_message) instead of strlen(tx_message). strlen() will stop counting when as soon as it reaches the first null character (0x00) in your array.

Best regards,

Vidar

Seems like the problem with receiving only zeroes still occurs. Reboot, reflash etc. nothing this time. Even tried swapping pc, then it worked for a time or two before zeros. Tried with differnt wires, nRF52840DK board, and different arduino.

Do you see the same problem with other projects such as UART Example too?

What are these wires used for?
