Thanks Robin ....
The nordic doc has the cct and pin under ( see GPS antenna section )
https://docs.rakwireless.com/Product-Categories/WisTrio/RAK5010-M/Datasheet/#hardware
I found the fix from examining the source in ..
https://github.com/espruino/Espruino/blob/master/libs/js/rak/RAK5010.js
The pin is defined but the code never turns the power on ?? ...
the comment says
line 118 // FIXME: GPS_EN pin?
GPS_EN is mapped to D39 in PINS earlier ...
So I used this in my code ..
//turn GPS antenna power on.
digitalWrite(D39,1);
sets the GPS antenna power on.
Checked it ( carefully ... ) with the voltmeter .... 3.6 volts with D39 set to 1 and zero volts when D39 set to 0.
So I my RAK 5010 is now kinda working for GPS ... I am using the setGPSOn from espruino site example code .. but the parsing is broken maybe because debug is now telling me Im getting position info from the GPS but I am getting broken output. ( which I wasnt before with the antenna power turned off ;-) ) ... I was not getting any output LOL.
