| Feb 4, 2020 at 18:37 | comment | added | Gabriel Gardin | @jcaron I read that it used to be problems when both the bluetooth and wifi was working together in the ESP32. But I think it's fixed because I managed to do so, just had to put a delay between the initialization of the wifi and bluetooth. | |

| Feb 2, 2020 at 21:02 | comment | added | jcaron | @GabrielGardin I’m not saying the ESP32 correctly handles WiFi/BT coexistence. I’m just saying that in theory it’s easier with both in the same chip. Whether Espressif implemented it (correctly) I admit I have no idea. | |

With a single antenna, you need to effectively stop one interface while the other is active. Most drivers are written with certain assumptions in mind, one of them being that the hardware doesn't just change state on its own. With a shared antenna, this assumption doesn't hold. | |

| Jan 28, 2020 at 13:03 | comment | added | jcaron | With two antennas using the same frequencies in close proximity, I doubt that it would be much better than a single shared antenna. And with a single chip handling both Wi-Fi and BLE you have at least a chance there is coordination between the two (they don't transmit at the same time), which you won't get with separate chips and antennas. | |
