OTA update using UART

DFU over UART is supported through the MCUmgr and the Simple Management Protocol (SMP) protocol, see https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/services/device_mgmt/mcumgr.html. Support for this can be enabled in the MCUBoot bootloader (serial recovery - DFU within the bootloader), or in the application as demonstrated by this sample: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html#smp-svr-sample

I have a board connected with nrf and the communication channel is UART.

So, UART firmware update would be required for the usecase that we are targeting.

Please give more information on the board you connected to. Does it has an MCU on it and you want to update it ?
Or you want to use the MCU on the board to update the NRF52. Please describe what exactly you want to achieve. How do you imagine the DFU update should be.

Hi Harsh,

Could you please clarify you want to do UART firmware update or OTA (over the air) firmware update ?
They are not the same.
Usually OTA update is via BLE and you use the phone to update. When with UART update you connect your board to PC or a device via UART cable.

Also please give more information about the motor driver that you want to update.
