I would like to update 51422 with MCU

[haunglru]

Hi

I would like to use the arm based energy micro MCU to update 51422 via UART I've understood how the firmware update example with hci, but I need a set of hci api to send hci packets from my MCU. so, I need a hci stack to do this, is it possible to use the dfu_transport_serial on other MCU ?

This isn't something we've tried, but I'd expect this to be doable, yes. Unfortunately it isn't really something we can help you with in detail, since we don't know much about other MCUs.

For other's reference, this question should also be helpful regarding implementing a HCI interface.
