Sentinel PX4 ( NO GPs Lock and firmware problem )
- 
					
					
					
					
 I've got some Sentinels that have been sitting on a shelf since last fall that I'm trying to get up and running for indoor flight tests. I've been running into some errors when trying to arm them via qgroundcontrol. For reference these are running with the microhard carrier add-on and two pMDDL2450 radios to communicate back and forth. I'm unable to enable GPS even after updating the EKF2_AID_MASK parameter, I get frequent MAG#0 Timeout warnings and I have a pretty high loss rate over MAVLink. Also when the vehicles are ready to arm and I can get the motors to spin for a second and then some failsafe is enable that shuts everything down and forces the vehicle to reboot. When that happens I get the following logs in the QGC console: ""_handleCommandAck command(MAV_CMD_COMPONENT_ARM_DISARM)result(MAV_RESULT_ACCEPTED)"" 
 "_handleCommandAck Ack not in list "MAV_CMD_COMPONENT_ARM_DISARM"I also get the following error when navigating around the vehicle settings in QGC: "Parameters are missing from firmware. You may be running a version of firmware which is not fully supported or your firmware has a bug in it. Missing paramsL 1:SDLOG_MODE" I'm wondering if any of this has to do with the voxl-px4 firmware and whether updating it would help. These are running voxl-px4 version1.12.31beta      Who I flashed release of the sentinels with the SDK 0.9.5 and to solve at least a few of the issues Are there specific steps ? 
 Please tell me the details that help to solve these problems and how we can get rid of them as soon as possible

 @Samer-Jaradat The missing params warning can be safely ignored

 @Samer-Jaradat Can you log into your drone with adb or ssh and enter the command px4-qshell gps status?
- 
					
					
					
					
 voxl2:/$ px4-qshell gps status 
 INFO [qshell] Send cmd: 'gps status'
 INFO [qshell] qshell return value timestamp: 2376085469, local time: 2376088441this is the result 
- 
					
					
					
					
 @Samer-Jaradat Okay, that's not very exciting. How about px4-listener sensor_gps?
- 
					
					
					
					
 voxl2:/$ px4-listener sensor_gps 
 never published
- 
					
					
					
					
 @Samer-Jaradat Okay, so that confirms that GPS driver has not been able to communicate with the GPS unit. Can you try journalctl --no-pager -b -u voxl-px4 > /tmp/test.txtand then attach the test.txt file so I can see all of the PX4 status and debug messages?

 voxl2:/$ journalctl --no-pager -b -u voxl-px4 > /tmp/test.txt

 @Samer-Jaradat Don't try to execute that file directly. It is used by px4. Just edit it, save it, and then reboot your drone.

 OK, but i don't know how we can edit it, 
 please tell me how i can edit it and save it.
