Durch speichern wir ein Restart initiiert und der ESP verbindet sich mit dem ausgewählten WLAN-AP und dem Broker. Dazu wird eine erste Anmelde Message geschickt. Der ESP wartet bis der Broker eine Start Senden Nachricht sendet. Daraufhin werden die Pakete vom Device (UART 100Byte) als MQTT Message zum Broker gesendet. Über den Broker können 3 Bytes direkt an das Device gesendet werden. Durch ein Byte aus dem Device oder aus dem Broker kann der ESP wieder auf Werkseinstellungen gesetzt werden.

Project: I have a device that uses an RF FG23 module from Silicon Labs, which transmits an FSK message at a frequency of 868MHz to a receiver that uses an si4463 module to receive the messages. I used a logic analyzer to connect to the SPI bus of the si4463 and intercepted the data transmitted by the si4463 to the MCU, including the device's shutdown command. This led to intercepting registers such as Frequency, Sync word, Bandwidth, etc. This information is necessary to create an over-the-air sniffer. What I expect from you is to create a sniffer with an si4463 receiver, such as (HC-12 si4463, E10-443MD-SMA, or even a CC1101 if you prefer), connected to an Arduino or an ESP32. This sniffer will need to be configured with the intercepted registers from the si4463. After the...
