We have several new Here3+. Every of them has no GPS fix even after 3 hours outside (I see uavcan_equipment_gnss_Fix2 message gets with 5Hz, but data is zeros).
I also tried to connect to M8P-2 via u-center (like described in Here3+ manual) to load almanach, but there is no “passThrough” parameter in Here3+ params. When I try do update M8P-2 software (like described in Here3+ manual) in u-center, it gets an error " 0.3 WARNING: SW Version information seems corrupt! 0.3 ERROR: Could not get correct ROM size"…
Does somebody know the way to connect to M8P-2 in Here3+ (in particular to load almanach)?
And what is the possible reason of few new Here3+ deviced has no GPS fix in described situation?
And maybe I can somehow to connect the developer to get the product support?
-Can you re-flash Here3+ firmware with MP ?
In UAVCAN window i press Menu->Update, then I see “Download FW”, then “File send complete”. I don’t sure does it mean that update is OK ot not.
-What is your LED indication on Here3+?
Right after I connect Here3+ to CAN1 (Cube Orange), the LED became solid White (or light Blue), and the color is always stays the same. No blinking or color change at all.
Can you please check the relative parameters ?
Yes I checked all the parameters, actually they are the same like in our Cube Orange with Here3 (which works OK). But I think the parameters is the second step. First step is that I have to see uavcan_equipment_gnss_Fix2 message with data instead zeros. Or I’m wrong?
Unfortunately, nobody helped to solve the problem. I was really surprized that the developer has no real documentation and technical support. It’s like some toy, but not serious device.
If I solve the problem, I’ll let you know. And you please share me the info, if you’ll find the way to make here3+ alive.
Yes, the same at my side.
Looks like the reason is in this note in the user manual:
" 4. HERE3 u-blox Chip Firmware Update
Here is 3 + U-Blox firmware update method will be released when a new firmware comes out for the M8P-2, the here3+ has the latest firmware at launch, and we will update here if a newer version comes out."
I think, this functionality just doesn’t implemented in Here3+…
yes! but I am getting only 5-6 satellite at a time. i think its only getting connected to GPS satellites its not getting connected to GNSS or Bidoue Satellites. do you have any solution for that? there must be problem with GPS_GNSS config.
