Wi-Fi TimeSync #2326

Closed pablo-mendoza closed 6 years ago

pablo-mendoza commented 6 years ago

It would be awesome to support Wi-FI TimeSync (https://www.wi-fi.org/discover-wi-fi/wi-fi-timesync) or some form of of high precision time synchronization (even if it only works between esp32s). I would allow for example to be able to implement multichannel wireless speakers.

@riataman esp32 does not support WiFi TimeSync. It will be supported on next WiFi chip.

@TimXia you think espnow would be fast/predictable enough to timesync two devices to 100uS?

TimXia commented 6 years ago

@riataman No, it can not. TimeSync can not work on ESP32 no matter what frame it uses.
