Is there a UART or SPI bootloader example for nRF51822?

[Bee]

Hello, everyone~

I need to connect nRF51822 and another big MCU with SPI. The big MCU is connected to a LTE module. The new firmware of nRF51822 need to be downloaded form the cloud, passed by the LTE module and the big MCU with SPI. So I want to ask for an example of the SPI or UART bootloader.

Thanks.

I would recommend taking a look at the HCI/UART Bootloader from SDK 11.

Thanks, Biorn. I didn't pay attention to it. It's just what I want.
