Summary

CfsBridge::subscribe(apid) can only produce telemetry-style message IDs (plus the special-cased FW_PACKET_COMMAND), so an application cannot subscribe to a standard cFS command MID such as a scheduler (SCH) wakeup message.

Adds:

CFE_Status_t subscribeCfsCommand(const ComCfg::Apid::T apid);
// MID = apid | CFS_BRIDGE_SPACE_PACKET_TYPE_MASK (0x1000) | CFS_BRIDGE_SPACE_PACKET_SEC_HDR_MASK (0x0800)

so e.g. APID 0x090 subscribes to MID 0x1890, matching cFS command messages carrying a command secondary header. Such messages then flow bridge → deframer → CfsRouter CFS_COMMAND route → SchAppDriver.

Used by JPL-Devin/fprime_cfs_reference#3 to drive the F Prime rate groups at 1 Hz from the real nasa/SCH app. Tested there against cFE main, draco-rc5, and v7.0.1.

Note: intended for fprime-community/fprime_cfs devel, but this session has no push/PR access to fprime-community — opened on this fork so it can be forwarded upstream.

Original prompt from michael.d.starch

We've just done a bunch of work on fprime-cfs-reference. Would you please edit that reference to include the sched app (not the lab, the real one). Configure it to dispatch messages at 1Hz. Then test and make sure the F Prime GDS -> fprime_app in cFS works and is reporting telemetry on the rategroup?

Then make a PR for any changes
