Miniplex BT Won't Connect to bluetooth
#1
Hi Everyone,
I am new to both Raspberry Pi, Raspian & Openplotter
I have been running Open CPN on a windows machine connecting to NMEA via Bluetooth through my Miniplex BT for several years now.
A dear friend put me onto Raspberry and Open plotter.

Athough I have been able to pair my Miniplex via the Bluetooth GUI, I have been unable to connect  to it.with the original GUI I always receive the message  " Connection Failed -No usable Services on this Device".

I then installed Bluez Bluemon which again allows me to pair and temporarly connect but then wont connect again.
I also have tried command line with Bluetoothctl.
Sudo bluetoothctl
agent on
default-agent
pair xx:xx:xx:xx:xx:xx
trust xx:xx:xx:xx:xx:xx
still no Luck
then I found in a different forum
sudo rfcomm bind 0 xx:xx:xx:xx:xx:xx
which forced the Bluetooth to connect for 30 secs.
I created a new serial connection in Open CPN using the RFCOMM 0 port
and witnessed that Open CPN received data from the Miniplex during this brief period of 30 Seconds.

could anyone please help me overcome this issue.
thanks in advance
