Will ESPNOW + WIFI + BLE work simultaneously

[rwel59]

I have an application with multiple ESP32's connected with ESPNOW to a master device that also connects to wifi. This all works great. I am now trying to add BLE functionality to the mix (for all devices).

In the wifi + espnow setup, esp_wifi_set_ps is set to WIFI_PS_NONE. When I remove this, most of the espnow transmissions get lost.

In the wifi + espnow + ble setup, I get 'Error! Should enable WiFi modem sleep when both WiFi and Bluetooth are enabled!!!!!!'.

Have not been able to find a definitive answer on whether these will work together but it doesn't look like it. Any input?

Set wifi mode (esp_wifi_set_mode) to WIFI_MODE_APSTA from WIFI_MODE_STA. This resulted in the error going away and seems like espnow packet loss has gone away. So all 3 services are now running simultaneously.

Haven't looked at the ramifications of making this change yet.f

Hi there,
I now it is an old topic, but I do have the same problem here...
Using ESP-IDF v4.4.1
"coexist: [1089473] Error! Should enable WiFi modem sleep when both WiFi and Bluetooth"
I have:

• mode set to WIFI_MODE_APSTA
• Bluetooth enabled
• ESPNOW: tried peer->ifidx = WIFI_IF_STA; and peer->ifidx = WIFI_IF_AP

But the espnow packets get lost and when I try to set esp_wifi_set_ps(WIFI_PS_NONE), it throws the coexist error.

I hope I can get some help here
Best regards from Germany!

Would you be willing to share a code snippled of your configuration, where the setup works?
That would be super great

Did no one else get this to work?
This is the last puzzle peace of my project
I really don't know what else to try.

I have found many tutorials online where they used both WIFI and ESP-NOW simultaneously with Arduino IDE. In this tutorial, they are receiving data from other esp devices over esp-now and sending to a web server with WiFi in STA mode. https://microcontrollerslab.com/esp32-e ... eb-server/

Hi There,
thank you This is not a problem to make it work. the main problem is all three together. I sadly finally found this Dokument:
https://docs.espressif.com/projects/esp ... exist.html
where it says that ESPNOW is not compatible with BLE.....
The wired thing is that I am pretty sure that I did have that running together (BLE+ESPNOW).
Adding another ESP would be soo much more complex in many ways

where it says that ESPNOW is not compatible with BLE.....

no it doesn't (it's a confusing table, but read the fine-print at the bottom) - it says espnow and ble and wifi (STA mode only) can all co-exist and are stable.
