Hi, we've used cheap GPS boards with an ESP32 before to get very accurate times at high frequency, by getting GPS time and using a Pulse-per-second pin on the GPS to give us a timer for the milliseconds.
On this board there is only a TX/RX connection to the ESP32 so no PPS pin we can use. Is there a way using the AT commands to achieve the same accuracy ?
