I’m having a weird issue with PH1 and RFD900+ telemetry when updating firmware to Copter 3.6.7 with ChibiOS bootloader, having the telemetry connected to Telem1 port.
(I’m not having that problem with 3.6.6 with NuttX bootloader)
When I power on the system with a battery, telemetry led turns to fixed red and I’m not able to connect through telemetry.
If I power on the system via USB, the telemetry led goes to green, and I’m able to connect to it through telemetry. If I connect a battery, while powered on through USB, I’m still able to connect via telemetry. Even if I disconnect the USB cable while is still powered though the battery, the telemetry module keeps working fine.
The first solution I found to have the telemetry working with PH1, AC 3.6.7 and ChibiOS bootloader, has been to connect the telemetry module to Telem2.
If I do that, I can power on the system with a battery without any telemetry problem.
(For me, PH2 and RFD900+ is working fine AC3.6.7 with both bootloaders. PH1 with 3dr telemetry is also working fine)
Is there any parameter or setup to make a PH1 with a RFD900+ telemetry module connected to Telem1 port work properly, or may be a ChibiOS-PH1 issue?
Thanks in advance,
