Have our prototype running with the HL7800. All seems to work fine except the GPS.
First, it takes the GPS almost a minute to get a GPS lock.
Secondly, and most strangely, when we do an at+gnssloc? we get a location that is about 30km away from our present location.
We are using an active ceramic antenna from Taoglas (pn: aggbp.25b), delivring about 3.5 volts to it. It’s capable of using up to 5 volts.
We are using firmware v188.8.131.52
