ESP32 Wi-Fi + BLE Eddystone beacon not advertising correctly #2600

Closed ayandas4 closed 5 years ago

ayandas4 commented 5 years ago

I'm facing a different issue in Arduino when trying to write an Eddystone beacon, along with Wi-Fi, EEPROM and few GPIO activities. After I added BLEDevice, I faced Sketch too big issue, and after I changed the default partition to increase the program memory area. I also tried selecting partition scheme "No Ota (Large APP)", the sketch too big issue gets solved.. But instead of Eddystone, it's advertising something else! Screenshot_20190321-104637

The debug log seem to suggests the advertisement set is completed. Am I missing setting some flag somewhere? Or something else is wrong?

Please let me know if anyone a dig deep and find the actual issue with this.

BLE initialization code:

BLEAdvertising *pAdvertising;
String product_url = "bit.ly/Brizo64a";

/*****************************************************************************
Initialize Bluetooth Low energy for Eddystone
*****************************************************************************/
void BLE_Init() {
  char beacon_data[36];
  uint16_t beaconUUID = 0xFFAA;   // UUID for Eddystone Service
  int url_length;
  int count;

  // Create BLE device
  BLEDevice::init("UniShelf");

  // Create BLE Server
  BLEServer *pServer = BLEDevice::createServer();

  pAdvertising = pServer->getAdvertising();

  //setBeacon();
  BLEAdvertisementData oAdvertisementData = BLEAdvertisementData();
  oAdvertisementData.setFlags(0x06);    // GENERAL_DISK_MODE 0x02 | BR_EDR_NOT_SUPPORTED 0x04
  oAdvertisementData.setCompleteServices(BLEUUID(beaconUUID));

  //beacon_data[0] = 0x20;    // Eddystone Frame Type (Unencrypted Eddystone - TLM)
  beacon_data[0] = 0x02;      // Length
  beacon_data[1] = 0x01;      // 
  beacon_data[2] = 0x06;      // 
  beacon_data[3] = 0x03;      // Length
  beacon_data[4] = 0x03;      // Flag - Complete list of 16-bit Service UUIDs data type value
  beacon_data[5] = 0xAA;      // 16bit Eddystone UUID
  beacon_data[6] = 0xFE;      // ...

  url_length = product_url.length();
  beacon_data[7] = url_length+6;      // Length
  beacon_data[8] = 0x16;      // Frame Type - Service Data
  beacon_data[9] = 0xAA;      // Eddystone
  beacon_data[10] = 0xFE;      // 
  beacon_data[11] = 0x10;      // Frame Type - URL
  beacon_data[12] = 0x00;      // Tx power 4dBm?
  beacon_data[13] = 0x03;      // URL Scheme Prefix - https://
  for(count=0; count<url_length; count++) {
    beacon_data[14+count] = product_url.charAt(count);
  }
  beacon_data[14+count] = 0xFF;

#ifdef DEBUG
  Serial.print("Beacon Data: ");
  for(count=0; count<url_length+15; count++) {
    if(beacon_data[count] < 16){
      Serial.print('0');
    }
    Serial.print(beacon_data[count], HEX);
    Serial.print(' ');
  }
  Serial.println();
#endif

  oAdvertisementData.setServiceData(BLEUUID(beaconUUID), std::string(beacon_data, url_length+15));
#ifdef DEBUG
  Serial.println("Service Data set!");
#endif

  pAdvertising->setScanResponseData(oAdvertisementData);
#ifdef DEBUG
  Serial.println("Scan response set!");
#endif
  // Start advertising
  pAdvertising->start();
#ifdef DEBUG
  Serial.println("Advertising started...");
#endif

  delay(5000);
}
