    Updating application firmware on EZ-BLE 012011 over UART from another micro-controller

    DheerajDake

      Hello, 

         

      I want to update the firmware on EZ-BLE 012011 over UART using another micro-controller. The .hex file containing the application firmware is stored in another micro-controller's flash. The file is then transferred to the EZ-BLE 012011 over UART which will flash the bluetooth module. 

         

      Currently, I am using MiniProg3 to program the EZ-BLE 012011. I am not sure what kind of bootloader is there by default in the EZ-BLE 012011 module(eval board). 

         

      Questions:

         

      1. How do I update/flash the bootloader in EZ-BLE 012011 to accept firmware over UART?

         

      2. If there a UART bootloader is built in already, what protocol should be followed to send the .hex file? 

         

      3. How to set the BLE module into bootloader state?

         

      Thanks
