I’m trying to use rtcm as dgps mode in an L86 without luck. These are the steps I am doing:
1- Set baudrate to 115200 with PMTK251
2- Send PMTK301,1 to enable rtcm and wait for the success response
3- Send via uart the raw messages from rtcm v3.0. (I also tried rtcm v 2.3)
result - All nmea GPGGA messages still say fix mode 1. It’s not using the rtcm data.
am I missing any step?
