Hi Gabriele,

So this is essentially solved then? Glad to hear it!

Let us know if there is anything else 🙂

Regards,

Hello,
I've found the problem is related to higher level flow.
The thread in charge of communication peeks data messages out of a fifo.
The critical code line is

while (true) {
struct comdrv_data_t *buf;
buf = k_fifo_get(&tx_queue, K_MSEC(5));

Changing the timeout to 10 ms helps to fill the transmission packet with more bytes.

Thank you
