When I have the screen in the Y position I cannot use the I2C. I can when in X position so 99.9% likely the pyboard is the problem and not the LCD (small chance X pos and LCD fits better because of the way I soldered but very, very unlikely). This is irritating because the Y position is the most use...

The solution was better soldering .

Solved this problem. Can I delete the post somehow?

OK and how did you thn proceed to make the actual Bluetooth communication work? I have an Android phone and a PC with Ubuntu. I can pair my Android phone to the JYMCU but have not managed to get around how to work with Bluetooth on Ubuntu. So what is the best approach to get Bluetooth working? After...

I got the LCD working in so far as I can write text to it and I can turn light on and off. However the light/backlight is not very strong, ot hardly makes a difference, the screen itself does not light up so I am thinking there is something wrong, that it is not soldered well enough or there is not ...

I cannot use those commands. I can only use send and recv. I try to do: uart=UART(3,9600) #Y9,Y10 => uart3 uart.send("AT") no response uart.send("AT+PIN5678") no change of pin, can still pair with old. So I can pair my android with the device and it blinks red but I cannot send commands successfully...

I would like to use the LCD, the Bluetooth module, the AMP and 2-4 servos in one application. That isn't possible right? Not enough pins. So use 2 python boards and perhaps CAN?

Anyone using the JYMCU bluetooth module? How did you get going? I can't find any instructions for Micropython for it. I connected it to Y9/19 and VCC and GND. Can I communicate with it via UART just to see if I get contact so it is correctly mounted? I have an Android phone and a PC to pair with lat...
