Feature Request: Allow data collection rates faster than GPS

[MattEttus]

Subject of the issue

GPS modules like SAM-M8Q output data at 10Hz. When logging from those, all other data collection is slowed down to the same rate, no matter what the setting is

Your workbench

• Attempting to log at 50 Hz, but limited to 10Hz b/c of GPS
• Artemis OpenLog v1.17
• How is OpenLog Artemis wired to your sensor(s)? Qwiic connector
• How is everything being powered? Battery
• Are there any additional details that may help us help you?
  From PaulZC in the forums -- "It would be possible to do this using the "autoPVT" function in the u-blox library. But it's not supported on the OLA at the moment..."

Steps to reproduce

Use GPS and attempt to log IMU at 50 Hz

Thanks Matt,

This should be straight forward to implement using autoPVT.

Cheers,
Paul

Hi Matt (@MattEttus ),

Thank you for your patience!

I have added the "autoPVT" feature. The code modifications are here:
44c319b

In the image below, you can see that the ZED-F9P is updating every 100ms, but the OLA is successfully logging data at 25Hz (every 40ms):

You will find the new option in the "Configure Attached Devices" menu for the GNSS.
I will leave this issue open until v1.8 is released - or at least until there is a BETA version you can test.
This should resolve the TOW issue too.
Very best wishes,
Paul

Hi Matt,
Firmware version 1.8 has just gone live. You can find update instructions here:
https://github.com/sparkfun/OpenLog_Artemis/blob/master/UPGRADE.md
And the new binary file is here:
https://github.com/sparkfun/OpenLog_Artemis/tree/master/Binaries
Please let me know if this fixes the issue. I've tested it here - but you never know!
All the best,
Paul
