Navio2 with M8Q-5883 external GPS+Compass setup issue

[ste (Lessie)]

Hi Svetlana,

Thanks for your help, I already tried and not works.
It’s have any way to check the data flow on ttyAMA0 device, please?

Looks like the Navio2 board don’t process the serial data from their UART port.

I already checked the external GPS module with a CP2102 USB to UART adapter on a Windows notebook with u-center software. However the M8Q-5883 module haven’t any non-volatile memory, the default baud rate is 9600 and the refresh rate 1000ms but works well and also if I re-configure for 115200 baud and 100ms refresh rate also working well.

I tried to add the USB/UART adapter into the Raspberry Pi but I wasn’t able to configure to get the serial signal anywhere.

I also read the following articles:

Navio2 with second GPS module

Hello, Some changes since 2017: /etc/default/arducopter is now like this: [Capture d’écran 2021-02-05 à 17.03.24] Before plugging GPS to UART Navio2 port, I checked configuration with UBlox utility and adjusted UART serial speed at 57600 and other parameters according to my need (I do not use GPS_SAVE_CONFIG option). I use the same method for the Navio2 GPS (ublox utility). [Capture d’écran 2021-02-05 à 17.09.41] Serial 4 is set at 57600 (same as M8N UART speed) and protocol at 5 (GPS) […

Unhealthy GPS signal on ArduCopter 4.0.3

Hi ! I’m very late to the party but I found the fix for the “unhealthy GPS signal”. If you are still here, does your GPS works well ? because mine doesn’t (or it comes from the EKF) and I’m trying to figure out why.

Unhealthy GPS Signal?

Hi I’m using the latest emlid raspbian image with ArduCopter 4.0.3 and Navio2. I’m having trouble with GPS, receiving an Unhealthy GPS Signal warning/error But the GPS has a 3d fix with 10+ satellites and HDOP under 1? What are the effects of this error, and how do I get rid of it?

Realy bad / unhealthy GPS in ardupilot

Ardupilot : V4.0.3 Image : the latest (did an update last week) Problem : The GPS is detected in Ardupuilot, the position is right (approx 2-5m of random slow deviation) while on ground with 10 sats. But there is a “unhealthy GPS” message in ardupilot and, while flying, LOITER and POSHOLD go everywhere. Hi, I’ve already made posts on the ardupilot forum about my build and another issue. This last issue was in part due to the GPS and was mainly due to the Extended Kalman Filter. The GPS vert…

Navio2 UART hardware control flow

Hi, Is it possible to enable hardware control flow in the Navio2 UART port? I noticed that in the pinout diagrams there are two pins in the UART port labeled IO17 and IO18. Can they be used as CTS and RTS pins? Thanks

…without any luck.
