Ble will not compile

Development Tools IDE 2.x
12

I see the situation is explained here:

If you have already upgrade your ESP32 development board to version 3.0.0 above, you need to change some code to compatible with it.

  1. BLEScanResults foundDevices = pBLEScan->start(scanTime, false); change to BLEScanResults* foundDevices = pBLEScan->start(scanTime, false);
  2. Serial.println(foundDevices.getCount()); change to Serial.println(foundDevices->getCount());

So change line 29 of the sketch from this:

BLEScanResults foundDevices = pBLEScan->start(scanTime, false);

to this:

BLEScanResults* foundDevices = pBLEScan->start(scanTime, false);

Then change line 31 from this:

Serial.println(foundDevices.getCount());

to this:

Serial.println(foundDevices->getCount());

After making those changes try compiling the sketch again. Hopefully this time everything will work as expected.
