I am a new bird for this MCU. My project has two part:
(1) Main program: Using the ST MCU (P/N: STM32F100C8) totransfer data in and out witha Bluetooth-module through USART interface and then to Android phone:
ST MCU <--> BT module <--> Android, (all communicate with each other by USART interface)
(2) Firmware update: I would like to do the firmware update function to update the main program byan Android phone which sending the update firmware to ST MCU throughBT-module by also USART interface.
I spent quite a lot of time searching method in this forum and other websites,
But I just cannot make sure some method like bootloader or DFU is the way I should
keep going. I have also checked many application note e.g. AN2606, AN3155 and AN3374... but seems that I do not have enough information to figure out the picture.
