[BeingVerified] Bluno and motor shield compatibility

Hello,
Not posting links, preview seems to be breaking them.

I have been using the L298P Shield V1.2, (SKU:DRI0009) to control motors with a Arduino Mega board.
I wanted to upgrade the boards I use, to the Bluno Mega board and control remotely. (SKU:DFR0323)

Unfortunately I can't control the motors anymore over the USB, nor over BLE. (over Serial)

Are there any ways I could make the shield compatible for the Bluno Mega ?
Is this a firmware issue? A routing issue for the BLE?

Best & thanks for any advice :D

2016-09-21 23:17:38 Hi gareth,

I did a test using the two controllers, the result is when I connected the shiled to Mega2560 via the USB, the motor can work well; when I connected the shiled to Bluno mega2560 via the mini USB, the motor didnt work indeed, but when I connected a external power supply to the board, the motor worked well.

It looks like a little strange. I measured the voltage of VIN pin on two controllers, there is voltage output on Mega2560, no voltage output on Bluno. So the motor connected to Mega2560 worked well, its the reason. But according to the schematic, the two VIN pin should be no voltage output. Now there is a possible reason is electric leakage on the VIN pin.

I will give a feedback to our team and any update will reply you immediately.

2016-09-21 06:07:09 I thought of supply only this morning.
I've been supplying the boards only through their USB during the debugging process.

I'm using a Arduino mega 2560 that connects with a USB-A and I had a response on my motors.

The Bluno Board connects with a Micro-USB cable, and this seems to not supply the shield enough. Connecting the mega board to the battery power my project has, everything went well!

I didn't think their would be such a big difference between an USB-A and a micro-USB cable!

Thanks for the suggestion!

2016-09-21 01:29:17 Hi Sir,

Which Arduino mega board did you use? 2560 or 1280? If its 1280, maybe you need to install the driver again. If its 2560, did you try to measure the voltage of the motor to make sure if the motor get powered? Or the code you didnt upload successfully?
