I reassembled my hexa-copter after a crash.
My vehicle configuration is,
- ArduCopter 3.6.7
- Pixhawk2.1 with cube black
- Here2 GPS
During the testing I found that Pixhawk2.1 is not detecting the Safety Arm Switch press for arming the vehicle. I tried another GPS module, still no luck. Then I tried same GPS in another Pixhawk2.1 in which the press is detecting and Red LED is changing from flashing to solid.
I checked he voltage at GPS connector and found 0V without pressing the switch and 3.3V while pressing the switch. Later I checked the continuity from GPS connector from the carry board to the STM32 pin inside the Cube. Electrical continuity is coming. I even tried re-programming the code, but still it is not detecting.
Is there any other troubleshoot mechanism to check why Pixhawk is not detecting the Safety arm switch press?
I did one flight test by disabling the " BRD_SAFETYENABLE" parameter, everything is okay.
