Description

This project allows remote configuration of an ADF4351 breakout board from a smartphone.

Smartphone talks bluetooth to an ESP32 module which in turn talks SPI to the module.

The module stores its configuration to the eeprom and reloads the latest configuration upon startup so the smartphone is only needed to change the configuration.
