Getting back to the "weekend project" sessions!
This weekend, I am working on the proxmark3 RDV4 again. Some time ago I programmed the reblay standalone feature to relay data over its HC-06 Bluetooth device in the Blue Shark add-on device: github.com/RfidResearchGr… 1/n
This weekend, I am working on the proxmark3 RDV4 again. Some time ago I programmed the reblay standalone feature to relay data over its HC-06 Bluetooth device in the Blue Shark add-on device: github.com/RfidResearchGr… 1/n
Knowing the limitations of HC-06 device, I decided to try something different for the communication. First, I had to find UART pins without breaking apart the Blue Shark. Removing the case in the back side, there are two pins without labels. That's our UART! 2/n
For testing purposes, I am using a small ESP32 from @adafruit adafruit.com/product/5405?g… with WiFi and BLE technology. The main purpose of the ESP32 is to see if I can relay data over WiFi with a MQTT 3/n
