ESP32 co-existence with 3rd party 802.15.4/BLE/Zigbee chipset?
Posted: Wed Dec 19, 2018 10:57 am
Hello Espressif technical support.
We would like to integrate 3rd party 802.15.4/BLE/Zigbee (probably Sub 1 GHz also) chipset with ESP32-PICO-D4, ESP32-WROOM or ESP32-WROVER module into our design. Due to the space constrain of our design those antennas are close proximity to each other in a very tiny device, thus the FCC Multi-transmitters/Antennas Co-location must be addressed first. The 802.15.4 chipset we choose has WiFi co-existence implemented base on IEEE 802.15.2 packet traffic arbitration (PTA) standard and can communicate with other compatible WiFi chipset via 2 or 3 wires.
As far as we know the ESP8266 has built-in HW register for the co-existence GPIO. But for the ESP32 variants there is no information regarding this radio system co-existence feature. This is mandatory when dealing with FCC and the other radio regulations.
May you please direct me to the information?
Thank you in advance.
