Hi Mike...

It always puzzled me why in your original list of commands you suggested the following 2 commands one after the other:

****14#200# heater off to -55 degr THIS IS THE VERY IMPORTANT COMMAND ****13#200# heater on to -55 degr

It would seem to me that command 1 turned the heater OFF and then command 2 just turned it back ON AGAIN! ....

Maybe you were just using "shorthand" and something else happens when you issue these commands one after the other?

Thanks!

Hi all,

A replay of the previous pass! All commands sent and acknowledged at 0939 UTC.

Beacon received at 0943 UTC: 00 compass ff0740150600002100009000ff

Solar Cell Voltage 5.00 V Solar Panel 6 Cur 43.92 mA Solar Panel 2 Cur 0.00 mA Solar Panel 3 Cur 37.65 mA Solar Panel 4 Cur 131.76 mA Solar Panel 5 Cur 401.57 mA EPS Reset Counter 0 Power Level Critical Battery Capacity Heater Active Battery Heater ON Power Safe Counter 0 Emergency Mode Counter 0 Battery Voltage 2.82 V Battery Current 0.00 mA Battery Temperature -1 °C

Heater still on - I think there is no internal communication between the units (I2C bus down). Mhh, I haven't got a clue.

Hi all,

I have one day off and tried to command COMPASS in full sunlight.

The first pass (for Europe) this morning was low, only 6°. All commands were accepted and confirmed several time by COMPASS.

At 0801UTC the beacon came with 00 compass ff0660000000002100009800ff

It shows, that the heater was still on - in spite of confirmed commands. I will try the next pass (nearly 90°).
