ESP32 co-existence with 3rd party 802.15.4/BLE/Zigbee chipset?

Postby Rivers » 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.

No he's asking about multiple antennas multiple radios which is different.

Particle argon has esp32+nrf52840

Did you ever get an answer here, Rivers? I'd like to know as well!
