SC originated report issue M10

0 votes
Hello all,

I am attempting to initiate an SC originated report to an M10 development board with a microchip dspic33. Right now I'm only using the pic and the M10 board (ie no sat comms - just testing the serial interface).

I've been able to send the Get Parameter command:
(85 12 08 00 ...) and received the expected response so communications are OK.

However when I try the SC Originated Report (ref Orbcomm specification document table 3.8):
(85 08 12 00 00 00 00 00 00 00 00 00 00 00 00 9d c4).

I received the following message from the M10:

"packet rejected, invalid parameter"

Any ideas as to what's going on? Since I'm not trying to connect to a satellite I didn't specify gateway info. Nonetheless I would expect an ACK from the M10 if the initial command was valid.

If you're sending the exact same packet that you've pasted above then you are missing a byte of data.
