Ive got a bluetooth module from hmsoft (4.o BLE smart) hooked up to my MEGA on ports 10/11 and on 3.3V/GND. I plug it into my usb port on my mac and my android can see it and even paired with it.
But for some reason I am unable to connect to the device once paired. What I mean by that is that at first I thought it was my poor understanding of appinventor2 and android studio, which could be because Im rusty on android. But then I downloaded about 10 apps from the play store which should at least connect to a bt device but they all hang after I pick the hmsoft module from the picker list:
BlueSPP (which I used before with an hc-05 that I no longer have)
ArduDroid
Bluetooth Terminal
Android Blue
BlueTerm
Bluetooth Terminal by some other dev
BT Simple Terminal
Arduino bluetooth
3 different android studio apps I have
2 different appinventor2 apps I made
I feel the connection may be requested to the bt module but it is not "accepted" automatically by the bt module. As if I had to do something on the bt module side to accept the incoming request.
Is there a way to view what the bt module is seeing? Like thru the dev/tty terminal or a program like Coolterm? I think this would require a usb-ttl module, right?
Can anyone guide me on this?
Thanks
