Hi. My drone is using PX4 firmware v1.16 running on QGC.
I learned that the parameters which are shown as missing (BAT1_V_LOAD DROP, BAT2_V_LOAD_DROP, BAT_N_CELLS, BAT_V_CHARGE, BAT_V_EMPTY) are in versions up to v1.15 and not included in v.16.
How do I downgrade to versions prior to v1.16 within QGC?
if you want to get pre-built fw for your board, check github releases. Releases · PX4/PX4-Autopilot · GitHub , go to preferred release and click Assets. not all releases have pre-built fw
