This project explores embedded RF development using Arduino on ESP32 LoRa hardware, implementing a CW Fox Hunt Beacon and a separate project for a dedicated receiver. The beacon transmits a user configurable, identification string, in Morse code at 12 WPM, followed by a 10-second carrier and 20-second pause cycle. It operates at ~10 mW, offering several hours of runtime on an 800 mAh battery. The firmware allows full parameterisation in code, including operating frequency, CW speed, transmit message, carrier duration, pause interval, and RF output power adjustable from -9 dBm to +21 dBm (0.12 mW–125 mW). ...

Block that receives a " message" and send string values over serial connection, to control hardware devices ( switch ), for example, via Arduino based controller ( see https://sourceforge.net/projects/ardu-switch/ ) Prerequisite: pyserial Build as usual for a Gnuradio block: - download and unpack - cd gr-message_to serial - mkdir build && cd build - cmake .. && make - sudo make install && ldconfig If successful this block is into OOT section...
