Here4 Blue RID Issue

Hi

Using the Here4 Blue RID with from time to time I get a PreArm failure saying: “OpenDronId: Invalid Location”. trying to trace the arducopter code it looks like it is originating in the RID module but at the time it happens the drone usually have RTK_Float or even RTK_Fix.
the only way I managed to get it to arm is after power cycle when it happens.
I tried looking up the error both on Ardupilot, Google and here but can’t find any answers.
Anyone else seen something like it?

Have you setup the GCS GPS? Ardupilot | opendroneid-panel

Hi

I did, and just to make sure it is clear the drone id works most of the time, but from time to time it will show the “OpenDronId: Invalid Location” and it will only be solved with power cycle.

I don’t even change anything on the GCS when it happens i just power cycle the drone since it is a udp connection it will reconnect and work properly, so i suspect it is a bug in the HERE4 RID code somewhere.

May I have the log while it’s running? and also the configuration you’re using

Good Day @guyzoler,
This message should simply indicate no valid GPS lock when trying to arm. For Drone ID, this applies to vehicle and GCS.

@Thomas Most of the time this happens the drone is at RTK_Float and the base is using the GPS from the RTK base which is a Emlid RS2+ unit which is also at RTK Float or FIx

@Cybra I’ll looks through the logs to see if i have an example, since we are not flying without RID I need to see if we had the Log_Disarm on…

@Cybra see example here, the drone had 27 sats and GPS Status of 5 but still sent invalid location

Which GCS are you using? Please take a screenshot of the GCS GPS section, and also the Here4 firmware version you’re using now
