ESP32-WROOM-DA-N8 Dual radio?

I need to have the ability to connect to both Wi-Fi and Bluetooth simultaneously. I wanted to use the ESP 32 and add a second radio module. My thought is the ESP 32 would handle the Wi-Fi connection and then the module would connect directly to a Bluetooth speaker.. I originally had used a Wemo d1mi...

I had to do this originally because I was using the d1 for WiFi and later needed to add Bluetooth and this was the easy solution, Now I have got to the point that I’d possibl...

our issue is as follows we are wemos D1 pin d4 connecting to a D 32 with pin 16 and the power from the D 32 is coming off the 3.3 V and ground on the d1 when we powered that way with the USB being plugged into the D1 we cannot make a connection to a Bluetooth speaker without pressing the reset butto...

Re: 32d fails to connect bt speaker when power anyting but micro usb

it belongs to the v3.2 branch, so I thought I could just simply get the commit and add arduino-esp32 as a component compile and get all the libs necessary. but its simply not working. the fix implemented on the commit mentioned above works perfectly but unfortunately is restricted only to esp-idf at...

Re: 32d fails to connect bt speaker when power anyting but micro usb

I do power it with 3.3v. Have tried with. 5 v also same problem

Only time I don’t have problem is if I power into micro usb


I’m not using WiFi I know they can’t coexist

The problem resolved if I push reset on board I have used a cap from en to ground thst did nothing
