Mcumgr based full modem update¶
The full modem update management library allows performing an update over UART using the SMP protocol, providing an API that exposes functions to register command hooks into the MCU manager (mcumgr) management protocol.
It is used by the nRF9160: Full modem firmware update using SMP Server sample to provide the following functionalities:
Modem firmware update to the modem
Memory hash function for write verification
It uses command value 0 for getting the hash of an address range and command value 1 for uploading firmware data.
MCUMgr based Full Modem Firmware Update(FMFU).
The Full Modem Firmware Upgrade (FMFU) is a module with functions that hooks into MCUMgr for doing a full modem update over a transport layer with the SMP protocol.
The command values are 0 for get_hash and 1 for firmware_upload
Setup and register the command handler for full modem update command handler group.
The modem library must be initialized in DFU mode before calling this function - nrf_modem_lib_init(FULL_DFU_MODE).
0 – on success, negative integer on failure.
