Can we do FOTA to other microcontroller which is connected with nRF51822?

I want to do firmware update over the air in a STM32F4xx microcontroller which is connected with nRF51822 chip via UART (TX, RX, CTS, DTR) and BOOT pins. ST microcontroller has a bootloader which can flash the firmware via UART peripheral when BOOT pin is low.

Please help me with this. Thanks in advance !

What difficulty are you having? Download the firmware update over BTLE in any way you please to the nordic chip, pull the boot pin on the STM low and feed the firmware to it over the UART.

Hello RK, I have done both examples independently sending and receiving messages over UART and FOTA for Nordic itself and both examples and it worked properly. But now when DFU is starting from bootloader and at which place I should add UART service, that thing I am not able to figure out. So my main question is, can you tell me where those data packets are coming in bootloader s110 example code?
