Hello,
we are currently testing the CubeSat kit as part of a university engineering project and encountered multiple issues with the Ground Station / telemetry system.
What works:
NRF communication appears functional
Wireless telemetry transmission works
IMU telemetry is received correctly
Battery voltage telemetry is received
Older Ground Terminal version can receive telemetry packets
What does NOT work
Newer Ground Terminal version fail to communicate properly
Serial communication attempts often result in:
"Transmission failed or timed out"
ASB data is received partially, but some ASB fields are incorrect or unstable. For example: AQI shows 0, TVOC/ECO2/CO2 show very low or suspicious values.
Solar cell voltage rapidly oscillates between:
25000 mV
0 mV
System states appear inconsistent
Important observation:
When:
latest satellite firmware is uploaded,
but an OLDER Ground Terminal version is used,
then telemetry partially works:
IMU data is visible,
voltage telemetry is visible,
packets are received continuously.
This suggests:
RF hardware is operational,
telemetry packets are transmitted,
but there may be:
packet format mismatch,
firmware/application incompatibility,
parser issue,
ASB firmware issue.
Additional observations
Telemetry console shows packets such as:
#I
#E
#D
#G
which confirms that packet transmission is active.
Tested
multiple COM configurations
direct serial testing using Serial Port Utility and PuTTY
multiple application versions
firmware reupload
MiniCore configuration verification
different baud rates
