DFU over BLE 1 bank

[thang47]

Currently my program is taking up more than half of the flash of nrf52833. But I want to DFU via BLE, is there a way to DFU 1 bank?

Hello,

Unfortunately, single bank DFU over BLE is not possible as the bootloader (mcuboot) does not include a Bluetooth DFU transport. The solution if you are running out of flash is to place the secondary mcuboot slot in external SPI flash.

Best regards,
