@HughB, I suspect we do not get response because
a) we call requests incorrectly. In the doc there are no description how to call a query, and no examples. Same as you, I just assume a query call should have no payload. That may be wrong assumption.
also there may be "a switch" that switches from NMEA to CASIC mode.b) the particular chip cannot not talk in CASIC mode. Just in NMEA.

I have tried exactly the same approach and nothing comes back. On Bangle1 sending CASIC commands via Serial1. write() would cause the response to come back via the GPS-raw callback but this does not happen on Bangle 2. Something we need @Gordon to comment on in the new year.
