Hi Alejandra,
the complete datagram is:
a4 03 40 00 5b 19 a5
and I just realized I falsly asked for 0x25 when actually this should have been 25 decimal, sorry.
I setup the module for continuous scan mode, extended messages, and it does work, no matter if that unexpected datagram comes up.
The module is connected to the pc via serial interface connected to an FTDI USB2RS232 bridge module (3.3V).
I get a RESPONSE_NO_ERROR for all of the setup commands. The AP2 module is hard reset before communication starts (RTS wired to Reset, wait for startup datagram).
Thanks for the support!
Best Regards,
Peter
