No worries. Sorry for the confusion here. There isn’t a handy table in any of gomspace’s manuals that I can use for clear illustration. There are just statements sprinkled throughout the manual. I looked through the code to get a clearer picture of how the obc directs data to the various ports when it processes a CSP packet as well as on other definitions set within the software. Based on this, I’ve outlined the OBC 's reserved ports below:
Port Name
0 — CSP_CMP
1 — CSP_PING
2 — CSP_PS
3 — CSP_MEMFREE
4 — CSP_REBOOT
5 — CSP_BUFF_FREE
6 — CSP_UPTIME
7 — AX100_RPARAM
9 — A3200_PORT_FTP
18 — A3200_PORT_FP
21 — A3200_PORT_HK
Any other ports are arbitrarily chosen to establish a connection. I hope this helps, but if I can clarify anything else here, please let me know!
