Sending Files from LoPy to Android device (e.g. Phone) via Bluetooth

[neilh93]

Hi All,

I'm looking to alter the code already provided by pycom to be able to send a text file from the LoPy to my phone.
I'm not sure if this is possible yet though with BLE only being supported and not "classic" bluetooth.

Does anyone have any tips or information about how i could do this possibly?

from network import Bluetooth

bluetooth = Bluetooth()
bluetooth.set_advertisement(name='LoPy', service_uuid=b'1234567890123456')

def conn_cb (bt_o):
    events = bt_o.events()
    if  events & Bluetooth.CLIENT_CONNECTED:
         print("Client connected")
   elif events & Bluetooth.CLIENT_DISCONNECTED:
         print("Client disconnected")

bluetooth.callback(trigger=Bluetooth.CLIENT_CONNECTED | Bluetooth.CLIENT_DISCONNECTED, handler=conn_cb)

bluetooth.advertise(True)

srv1 = bluetooth.service(uuid=b'1234567890123456', isprimary=True)

chr1 = srv1.characteristic(uuid=b'ab34567890123456', value=5)

char1_read_counter = 0
def char1_cb_handler(chr):
global char1_read_counter
char1_read_counter += 1

events = chr.events()
if  events & Bluetooth.CHAR_WRITE_EVENT:
    print("Write request with value = {}".format(chr.value()))
else:
    if char1_read_counter < 3:
        print('Read request on char 1')
    else:
       return 'ABC DEF'

char1_cb = chr1.callback(trigger=Bluetooth.CHAR_WRITE_EVENT | Bluetooth.CHAR_READ_EVENT, handler=char1_cb_handler)

srv2 = bluetooth.service(uuid=1234, isprimary=True)

chr2 = srv2.characteristic(uuid=4567, value=0x1234)
char2_read_counter = 0xF0
def char2_cb_handler(chr):
    global char2_read_counter
    char2_read_counter += 1
    if char2_read_counter > 0xF1:
        return char2_read_counter

char2_cb = chr2.callback(trigger=Bluetooth.CHAR_READ_EVENT, handler=char2_cb_handler)
