Hello,
I rent Skydemon for the month in order to use it with GPS BU-353N5.
I try to connecte and use BU-353n5 GPS as external device.
1) In windows device manager (all default setting) : COM6 Baud 4800 (Data:8,parity:none,Stop:1,flow:none).
2) in Skydemon : Setup : COM6 baud 4800 : "I have a Skydemon Mobile device".

Unfortunatly when I do : Go Flying --> connect to RS232 GPS hardware, the message "Seeking GPS Satellites" and no GPS data seems to be received.

Skydemon version : 3.16.13.0
driver Prolific PL2303GC USB serial COM port : 5.1.6.0

I wonderring if there is a command line instruction that has to be sent to the BU-353N5 in NMEA protocol in order to be recognized by Skydemon.

Could you help me please ?

Best regards

Sorry, we have no experience of that device. The modern way to use a GPS device on a Windows PC is to pair it through Windows and then let SkyDemon use Windows Location Services to show your position.
