Esp8266 + ble_proximity

Hi,

Did any body manage to add MH09 to ESP8266 as custom c++?

I am trying with:

This is my code:

#include <esphome.h>
#include <SoftwareSerial.h>
#include <CDBLEProx.h>

void ble_event(BLE_PROXIMITY_EVENT eventArgs);
SoftwareSerial sw(D1,D3);
CDBLEProximity ble(&sw,ble_event);

class BLE_Prox : public Component {
 public:

  void ble_event(BLE_PROXIMITY_EVENT eventArgs) {
    if (eventArgs.eventID==BLE_EVENT_ON_DEVICE_LOST) {
        Serial.println("No device");
        Serial.println("");
        //ESP_LOGD("custom", "Something");
    }
    if (eventArgs.eventID==BLE_EVENT_ON_DEVICE_APPROACH) {
        Serial.println("New device");
        //Serial.print("MAC: "); Serial.println(eventArgs.device.mac);
        //Serial.print("HL : "); Serial.println(eventArgs.device.hilo);
        //Serial.print("HI : "); Serial.println(eventArgs.device.hi);
        //Serial.print("LO : "); Serial.println(eventArgs.device.lo);
        //Serial.print("SIG: "); Serial.println(eventArgs.device.rssi);
        //Serial.println("");
    }
    if (eventArgs.eventID==BLE_EVENT_ON_DEVICE_MOVED) {
        Serial.println("Device moved");
        //Serial.print("MAC: "); Serial.println(eventArgs.device.mac);
        //Serial.print("HL : "); Serial.println(eventArgs.device.hilo);
        //Serial.print("HI : "); Serial.println(eventArgs.device.hi);
        //Serial.print("LO : "); Serial.println(eventArgs.device.lo);
        //Serial.print("SIG: "); Serial.println(eventArgs.device.rssi);
        //Serial.println("");
    }
  }

  void setup() override {
    Serial.begin(9600);
    ble.begin();
  }

  void loop() override {
    ble.update();
  }

};

But I get:

/home/seeb/.platformio/packages/toolchain-xtensa/bin/…/lib/gcc/xtensa-lx106-elf/4.8.2/…/…/…/…/xtensa-lx106-elf/bin/ld: .pioenvs/mini4/src/main.cpp.o:(.text.startup._GLOBAL__sub_I_logger_logger+0x8): undefined reference to `ble_event(BLE_PROXIMITY_EVENT)’

I don’t see where you declared an instance of ble_event.
Also, in the future, post the error messages in code tags.
