In the past I used Iridium Modem with two kind of protocols: connection mode (Rudics) and message based.
If I understood correctly the Artemis Global Tracker is configured to work with the RockBLOCK provider and it’s message based. I need to send a block of data that can be 8Kbytes.Do you know if it can be used with other provider that support connected mode?
With connected mode I mean that the Modem make a call to another modem to establish a TCP connection.
The Artemis Global Tracker uses the Iridium 9603N modem which is only capable of Short Burst Data (SBD) transfers. It is not like the other Iridium modems which support connected mode. You would need to divide your 8K of data into 340 byte chunks and transfer them one at a time.
If you want to transfer all 8K bytes to another modem, you are actually limited to 270 bytes per message. The limits for SBD transfers are 270 bytes received, 340 bytes transmitted.
