Flash firmware using Bluetooth


Using the native built in bootloader of STM32, the firmware can be programmed using Bluetooth. Please see this important information.

Hardware



To use the native bootloader of STM32, B0 pin of STM32F103 need to be connected to 3.3V at reset time. The B0 pin is connected to GND on the board by a resistor but is also available on J15 header (Bluetooth header).

To force entering the bootloader, wire the B0 pin to 3.3V pin on the J15 header (the adjacent pins). After reset the board, the bootloader will always start while that pins are wired and will be ready to flash the firmware.

NOTE: the STATE pin of the Bluetooth module don't seem to work/be wired - the pin never changes to 3.3V when module is connected/LED always ON).

Software



On Linux Ubuntu you can install from repositories:

You can also get stm32flash from the project page: https://sourceforge.net/p/stm32flash/code/ci/master/tree/

• Prepare the /def/rfcomm0 device

Get device information:
sudo stm32flash /dev/rfcomm0 -b 115200

Write with verify and then start execution:
sudo stm32flash -w filename -v -g 0x0 /dev/rfcomm0

NOTE
As of 2017.04.27, the flashing didn't work and I got this output:
sudo ./stm32flash /dev/rfcomm1 -b 115200
stm32flash 0.5
