BLE data from another esp32

Hi,

is it possible send data from another esp32 to OMG?

i am using this library GitHub - lucascoelhof/ESP32BleAdvertise: Simple library for BLE advertise using ESP32 in Arduino

i see my esp32 device in mqtt data OMG send, but there is only ID, name and rssi data, no servicedata

when i use BLE scanner on my phone, servicedata is visible

thank you for your help

Hi,

Yes it should be possible. You may use the examples from nimble arduino

github.com

h2zero/NimBLE-Arduino/blob/master/examples/NimBLE_Service_Data_Advertiser/NimBLE_Service_Data_Advertiser.ino

/** NimBLE_Service_Data_Advertiser Demo:
 *
 *  Simple demo of advertising service data that changes every 5 seconds

 *  Created: on February 7 2021

#include <NimBLEDevice.h>

#define SERVICE_UUID "4fafc201-1fb5-459e-8fcc-c5c9c331914b"

static NimBLEUUID dataUuid(SERVICE_UUID);
static NimBLEAdvertising *pAdvertising = NimBLEDevice::getAdvertising();
static uint32_t count = 0;

void setup() {
  Serial.begin(115200);
  Serial.println("Starting BLE work!");

This is the library we use. So it may have better compatibility
