bluetooth.service and characteristic correlation

This is my code to set BLE settings..i do not see how these values relate to what my mobile app detects...see image

bluetooth.set_advertisement(name=devicename, service_uuid=b'1234567890123456')
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
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
char2_cb = chr2.callback(trigger=Bluetooth.CHAR_READ_EVENT, handler=char2_cb_handler)

When you do this:

b'1234567890123456')

You're creating a list of bytes based on the ASCII value of each digit (1 = 0x31, 2=0x32 3=0x33 etc)

Your phone however shows you the hexadecimal representation of each byte. It also has a different byte ordering but you can see the b'123...' in "...33-3231" - it's just in reverse order

See my previous post on how to produce services that look as you expect:
