Feature request

Is your feature request related to a problem? Please describe.

Right now, there is no way to enable the internal logging on the PX1 GNSS because the API is only available over the ethernet web UI. Internal logging is used for tech support to analyze system performance. Since PX1 has little flight hours on small fixed wing drones, this is particularly useful to have the ArduPilot community be able to supply logs.

Describe the solution you'd like

Consume GPS_RAW_DATA in AP_GPS_GSOF
Handle disabling logging on disarm, and log continuation on arm
Send enable logging/disable logging commands as appropriate
Stretch: Handle runtime param updates
Update wiki entry for PX1: https://github.com/ArduPilot/ardupilot_wiki/pull/5540/files
Create follow up issue for dealing with log data filling up and whether old logs are overwritten, the user is notified that logs are full, or something else

Describe alternatives you've considered

Further details

The following binary data commands are what need to be sent for logging. There is no TransNumber, so just hard code these in the implementation file. If there is an ACK, parse the ACK.

Start Logging: 02 00 4C 09 08 44 45 46 41 55 4C 54 00 62 03 
Stop Logging: 02 00 4C 09 09 44 45 46 41 55 4C 54 00 63 03

Dependencies

The configuration ack/nack pattern from gsof-49-50 branch needs to be merged in before there is ability to do configuration responses. This ticket could be done without acks, however it will need to be changed.

研究方向: Investigate the current implementation of AP GPS GSOF (likely in libraries/AP GPS/AP GPS GSOF.cpp). Understand the binary command structure for starting/stopping logging as provided in the issue. Check the status of the dependency on the gsof 49-50 branch for configuration responses. If that branch is not yet merged, consider whether the implementation can proceed without acks, but be prepared to update later. Also review the GPS RAW DATA parameter and how internal logging is typically enabled in ArduPilot.
