      Hello,
      I am using VOXL2 with SDK 1.1.2 installed. I am facing very strange issue with Holybro M8N GPS on J19 connected to VOXL2. This GPS takes very long time to actually start to publish GPS data on sensor_gps topic. I changed GPS, VOXL2, cable everything in my custom drone setup still this issue isn't getting solved. The time to publish data over sensor_gps as I said is very random and what I can see on logs as shown below is this GPS module keeps printing Baudate and verrsion info and after long time actually starts to publish sensor_gps topic.

      Logs :

      Please help urgently over this problem @Alex-Kushleyev @Eric-Katzfey since I am stuck with this issue since last two days.
      @Alex-Kushleyev just FYI this is the same custom drone with M0065 firmware for controlling 8 actuators which you shared with me, I am just keeping these two issues separate.

        @Aaky Can you try an experiment? Can you change qshell gps start to qshell gps start -b 38400 in /usr/bin/voxl-px4-start and see if that helps?

          @Eric-Katzfey It seems to be working fine with

          qshell gps start -b 115200

          Still trying to do stress testing.

            @Aaky , we are working on resolving the GPS detection issue related to uart baud rate changes - if forcing the baud rate works reliably then just stick with that !
