Hi,

NDA problems,

Wi-Fi and the BT simultaneously: Yes.
SW implementation: don't touch Arduino.

Add me if you wish to discuss implementation further.

We have also implemented similar stuff with a esp8266.

Regards,

Great to know! Have you operated both the Wi-Fi and the BT simultaneously? Are there any design guidelines or SW implementation?

Hi,

I have used both these chips on the same PCBs with no issues at all (about 5mm spacing).
Note: The nRFs are Raytac MDBT50Q-1MV2 and the ESP32 is a ESP32-WROOM.

Hi,

The two certifications should be valid for both modules. We currently don't have a coexistence interface for the Softdevice, but the Wi-Fi might have one. Radio activity can be signaled by setting a pin as we do for supporting PA/LNA in S132.
