Macro Definition Documentation

◆ FIRMWARE_PROTOCOL_31

#define FIRMWARE_PROTOCOL_31

Enabled FOTA 3.1 protocol extensions.

Supports smaller FIRMWARE_BLOCK_SIZE, RLE and NVM for nRF5 with mcuboot. The extension is enabled per default when mcuboot is present or full FIRMWARE_BLOCK_SIZE exeeds MAX_PAYLOAD_SIZE.

Function Documentation

◆ firmwareOTAUpdateProcess()

LOCAL bool firmwareOTAUpdateProcess ( void  )

Handle OTA FW update responses.

This function handles incoming OTA FW packets and stores them to external flash (Sensebender)

◆ readFirmwareSettings()

LOCAL void readFirmwareSettings ( void  )

Read firmware settings from EEPROM.

Current firmware settings (type, version, crc, blocks) are read into _fc

◆ transportIsValidFirmware()

LOCAL bool transportIsValidFirmware ( void  )

Validate uploaded FW CRC.

This function verifies if uploaded FW CRC is valid
