Description

This project retrieves the current time via NTP and synthesis the BPC time signal using the ESP-32. The ported version is compatible with the NodeMCU-32S, although my CITIZEN watch did not accept the signal.

Hardware

Circuits

In this fork, GPIO16 is used to transmit the modulated carrier wave. The circuit setup follows the "longer range" configuration from harlock974/time-signal. Alternatively, you can use the circuit from botanicfields/BF-018A.

Running the Sample

1. Acquire an ESP-32 compatible development kit and prepare the necessary development environment.
2. Assemble the circuit.
3. Compile and upload the bpc.ino file to the NodeMCU-32S.
