How to upgrade NRF52832 to DFU through UART.

[RDL_ZYL]

We currently have a project that requires downloading firmware through 4G and transmitting it to NRF52832 through serial port for DFU. Do you have any relevant routine code for me to refer to?

Hi,

The format and storage location is described in the Documentation for SPI DFU Master in the tutorial: DFU_SPI_readme.docx

The DFU protocol is also documented in our SDK documentation.

Best regards,
Jørgen
