3.4.1.2 Serial Bridge Application to Upgrade ATWINC1510 Firmware and Root Certificates

Description

This application hex file acts as a serial bridge between the PC utility (winc_provisioner) and the ATWINC1510 module on SAM IOT board.

The application interfaces with the PC over UART and with the ATWINC1510 module over the SPI lines.

The application receives the ATWINC1510 firmware and root certificate bundle from the PC, and programs it into the ATWINC1510 module.
