how to enable wifi-bluetooth co-existence feature in esp8266

Postby samueloriginal » Tue Jul 18, 2017 3:49 am

There is hardware register for the co-existence gpio. But there is no information how to use it. Also there is no software routine to control/setup it.
May you direct me to the information?

From the rtos_sdk_programming_guide_en.pdf:
The ESCP–Espressif Systems’ Smart Connectivity Platform has many cutting-edge advantages, including energy-efficient VoIP that can switch rapidly between sleep and wake modes, adaptive radio bias for low-power operations, front-end signal processing capacity, problem shooting capacity, and the radio system co-existence feature to remove cellular, bluetooth, DDR, LVDS and LCD interference.

From the esp8266_technical_reference_en.pdf:
