Witam,

Za pomocą poniższego kodu łączę się z licznikami energii w zależności od podanego adresu MAC.

Kod:

#include "BLEDevice.h"

static BLEUUID srvUUID("0000ffe0-0000-1000-8000-00805f9b34fb");
static BLEUUID chrUUID("0000FFE1-0000-1000-8000-00805F9B34FB");
String BLE_Address1 = "47:71:f7:a7:25:93"; // adresy MAC
String BLE_Address2 = "47:71:f7:a7:14:f2";
static BLEAddress *Server_BLE_Address;
static BLEAdvertisedDevice* scale;
static BLERemoteCharacteristic* remoteChr;
static boolean doConnect = false;
static boolean connected = false;
static int year = 0;

static void chrCB(BLERemoteCharacteristic* remoteChr, uint8_t* pData, size_t length, bool isNotify) {
   
double spr = 0;   
spr  = (pData[0]);
if (spr == 255) {
   
  Serial.print("Data bytes: ");
  for(int i =0; i< length; i++){
      Serial.print(pData[i]);
      Serial.print("  ");
    }
    Serial.println(" ");
    
double dana1 = 0;
dana1 = (((pData[5]*256) + pData[6]+ pData[7]) ) ;
dana1 = dana1/10;
double dana2 = 0;
dana2  = (((pData[8]*256) + pData[9]+ pData[10]) ) ;
dana2 = dana2/1000;
double dana3 = 0;
    dana3  = (((pData[11]*256) + pData[12]+ pData[13]) ) ;
    dana3 = dana3/10;
Serial.println("Wartości pobrane: ");
Serial.print(" - ");

    Serial.println(dana1,1);

    Serial.println(dana3,1);
    Serial.println(" ... ");
} 
}

        scale = new BLEAdvertisedDevice(advertisedDevice);
        doConnect = true; 
      } else {
        Serial.print(".");
      }
    } else {
      Serial.print(".");
    }
  }
};

class ClientCB : public BLEClientCallbacks {
  void onConnect(BLEClient* pclient) {

  void onDisconnect(BLEClient* pclient) {
    Serial.println("Disconnected. Reconnecting...");
    connected = false;

bool connectToScale() {
    Serial.println("Stablishing communications with scale:");
    BLEClient*  pClient  = BLEDevice::createClient();
    Serial.println("    BLE client created");
    pClient->setClientCallbacks(new ClientCB());
    pClient->connect(scale);
    Serial.println("    Connected to scale");
    BLERemoteService* pRemoteService = pClient->getService(srvUUID);

    return true;
}
void setup() {
  Serial.begin(115200);
  Serial.println("Searching for AT24CB-BLE device");

  delay(1000);
  BLEDevice::init("");
  BLEScan* pBLEScan = BLEDevice::getScan();
  pBLEScan->setAdvertisedDeviceCallbacks(new deviceCB());
  pBLEScan->setInterval(1349);
  pBLEScan->setWindow(449);
  pBLEScan->setActiveScan(true);

Łączę się bez problemu po zmianie 

BLE_Address1 na BLE_Address2

w tym miejscu

Kod:

if((advertisedDevice.getName() == "AT24CB-BLE") && (adres == BLE_Address1)){

Nie wiem jak połączyć się z dwoma licznikami i otrzymać z nich dane.
Z góry dziękuję za podpowiedź.
