Connecting simpleRTK2B with Pixhawk 4

Ioannis asked 3 weeks ago

We recently purchased a simpleRTK2B+Heading module and we are trying to connect it using the JST connector on the simpleRTK2B (big board) and connecting it to the Telem1 port of a Pixhawk 4. 
Although we have success using ArduRover 4.1.0-dev we don’t want to use this version as it has too many bugs and our project is for commercial use. So we have to stay with the stable version 4.0.0 for now. 
Could anyone guide us if it possible to achieve this using the stable version? What parameters do we have to change (below you can find the relevant parameters we are using right now with the the ArduRover 4.1.0-dev)? 
COMPASS_ENABLE,0
COMPASS_USE,0
COMPASS_USE2,0
COMPASS_USE3,0
EK3_MAG_CAL,5
EK3_SRC1_YAW,2
GPS_AUTO_CONFIG,0
GPS_AUTO_SWITCH,0
GPS_POS1_X,-1.3
GPS_PRIMARY,1
GPS_RATE_MS, 100
GPS_RATE_MS2, 100
GPS_TYPE,0
GPS_TYPE2,18
SERIAL1_BAUD,115
SERIAL1_OPTIONS,0
SERIAL1_PROTOCOL,5 
P.s We followed a relevant guide (https://www.ardusimple.com/ardupilot-simplertk2bheading-configuration/) of one of the latest blog post and it helped us a lot but it was based on the ArduRover 4.1.0-dev.
Thanks in advance!

Hi Ioannis,
We tried with version 4.0.0 but we could not make it work.
We don’t know if we missed some parameter in the configuration or if this version does not support GNSS based heading.
Best regards,
ArduSimple Team

Hello again,
What you will do with your product since Ardurover is sticked with version 4.0.0?
We purchased a product that practically doesn’t work as advertised.

Hello Ioannis,

In the product description we do not mention (yet) any compatibility with Ardupilot and in the post where you found the tutorial we mention explicitly that we tested the heading kit with version 4.1.0-dev of ArduRover, ArduCopter and ArduPlane.
This is also mentioned in the official ArduPilot documentation site: https://ardupilot.org/copter/docs/common-gps-for-yaw.html
We recently joined Ardupilot partners program to involve ArduSimple with the project and get a better overview of their development timelines. We will ask the developer team if an official 4.1.0 release is expected soon.

Best regards,
ArduSimple Team
