Hi, can I use this board to connect to a LED matrix, and load the displaying text (or graphic) from an Android phone wirelessly via bluetooth connection?

We are not sure if Bluno M3 support MBED, and the Bluno M3 is to using Arduino with STM32 as the main controller, so the firmware is for arduino development. If MBED is compatible as you said, you may need to totally refresh the firmware, and develop the whole environment.

Hi
We haven't developed this function in Bluno library. You may need to write the function yourself.

Hi there!
I just bought one of these thinking I could use mbed (https://os.mbed.com/) on it. Is it possible? What is needed to achieve this?
The issue I run in, it that the board is not recognised by mbed as a target..

Thanks a lot!

the Bluno has multiple serial ports. You need like
Serial1.begin() or Serial2.begin() until Serial4

Hi, I just bought the Bluno M3 V 2.2 but everytime I try to upload a sketch it says :
serial_read1byte had problem, exiting
: No error
WARNING: trycount in serial_read1byte = 2
WARNING: trycount in serial_read1byte = 3
WARNING: trycount in serial_read1byte = 4

Are you sure, it is V2.2? If I'm right, Bluno M3 V2.2 is not released. it still V2.1

I have one of these and I think it has a serious issue, probably firmware, where it can get into a state where you can not upload a sketch.

HI, Bluno M3 is based STM32 microcontroller, it is a little difficult to use this kind of product. Have you install the driver successfully? which IDE are you using now? We customized an Arduino IDE 1.5.5. You can download it on wiki. And if you have any question. it is better to post them on the forum.
