Trying Bluetooth on Arduino - "NVDS MAGIC FAILED"

[mydadisaplumber]

Hello, I downloaded the Arduino core, and got a "Hello World" up and running. I noticed that there was a "SimpleBLE" example included, so I was assuming that Bluetooth had been added to the Arduino interface (I can't find much to confirm or deny this). I upload the sketch (which looks like it just advertises) fine. However my serial output is:

Code: Select all

The data at the top of the debug is from 2016. Do I have an old version? Is Bluetooth even implemented yet in Arduino? Thanks.

I get the same message "NVDS MAGIC FAILED". Bluetooth works despite that msg.

I've tried to look but my phone can't see the BT network. The error occurs on the ble.begin command, so I have

Code: Select all

ble.begin("ESP32 SimpleBLE");
Serial.println("Did we get here yet?");

and the second line never prints, leading me to the think it's in an error state.

SimpleBLE is a ble advertisement beacon, try a beacon scanner app for your phone.

And maybe some debug printlines in SimpleBLE sources

I tested SimpleBLEDevice and I see error:

I have the same NVDS MAGIC FAILED message but the bluetooth still works
