I recently got a new set of SiK HM-TRP radios with the intention of just using the air-module for a new craft. However, it wouldn’t connect with my existing base station which after some diagnosis I put down to it being a newer version of firmware. So, I took the 1.9 firmware from RFDesigns site since all my other craft are running 1.9 or earlier along with my base station. However, after flashing with this firmware it still will not connect. On closer examination it seems the ‘Format’ parameter is ‘26’ rather than ‘25’ as is the case with all my other radios.
I presume this is enough to block it?
