I am having trouble getting the ESP 32 Dev board to compile and load for my project. I am trying to open a Bluetooth scanner to get the UUID of my device, but I cant even get the board to connect. Heres the error message:
/Users/megan/Documents/Arduino/libraries/ESP32_BLE_Arduino
exit status 1
Error compiling for board ESP32 Dev Module.
Please post your sketch and full error message using code tags for both
for using board ESP 32 Dev Module
sketch:
#include <BLEDevice.h>
#include <BLEUtils.h>
#include <BLEScan.h>
#include <BLEAdvertisedDevice.h>
int scanTime = 10; //In seconds
int minimumDeviceThreshold = -60;
BLEScan* pBLEScan;
class MyAdvertisedDeviceCallbacks: public BLEAdvertisedDeviceCallbacks {
void onResult(BLEAdvertisedDevice advertisedDevice) {
int rssi = advertisedDevice.getRSSI();
if(rssi > minimumDeviceThreshold){
Serial.printf("Advertised Device: %s \n", advertisedDevice.getServiceUUID().toString().c_str());
//Signal strength
Serial.print(" RSSI: ");
Serial.println(advertisedDevice.getRSSI());
}
}
};
void setup() {
Serial.begin(115200);
Serial.println("Scanning...");
BLEDevice::init("");
pBLEScan = BLEDevice::getScan(); //create new scan
pBLEScan->setAdvertisedDeviceCallbacks(new MyAdvertisedDeviceCallbacks());
pBLEScan->setActiveScan(true); //active scan uses more power, but get foundDevices faster
pBLEScan->setInterval(100);
pBLEScan->setWindow(99); // less or equal setInterval value
}
void loop() {
// put your main code here, to run repeatedly:
BLEScanResults foundDevices = pBLEScan->start(scanTime, false);
Serial.print("Devices found: ");
Serial.println(foundDevices.getCount());
Serial.println("Scan done!");
pBLEScan->clearResults(); // delete results fromBLEScan buffer to release memory
delay(2000);
}

Sorry, I dont know what code tags are
Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'
Use [color = red]code tags[/color] (the </> icon above the compose window) to make it easier to read and copy for examination
