Unable to connect to any BLE device

[Youssef Elwakil]

Hi there,

I am struggling to connect my Gpy device to any BLE device such as my iPhone and PC. Nothing is showing up and when I want to connect using its name it doesn't work.

Code:

from network import Bluetooth
import time
bt = Bluetooth()
bt.start_scan(-1)

while True:
  adv = bt.get_adv()
  if adv and bt.resolve_adv_data(adv.data, Bluetooth.ADV_NAME_CMPL) == 'GNZ-PC2710':
      try:
          conn = bt.connect(adv.mac)
          services = conn.services()
          for service in services:
              time.sleep(0.050)
              if type(service.uuid()) == bytes:
                  print('Reading chars from service = {}'.format(service.uuid()))
              else:
                  print('Reading chars from service = %x' % service.uuid())
              chars = service.characteristics()
              for char in chars:
                  if (char.properties() & Bluetooth.PROP_READ):
                      print('char {} value = {}'.format(char.uuid(), char.read()))
          conn.disconnect()
          break
      except:
          pass
  else:
      time.sleep(0.050)

@Youssef-Elwakil are you running an app on your phone or your PC that advertise something?

Use a BLE scanner app on your phone. If that app can’t detect the device, neither will the GPy.
