Accessing Minor & Major from iBeacon scan
Using ADV_MANUFACTUER_DATA I can cleary see the UUID of the iBeacon I am scanning for. However I cannot view the Major, although I believe I can see the Minor. Obviously to gain the full use of Ibeacon I need to see the minor and major identifiers.
This is the output of the below code -> 4c0002152f234454cf6d4a0fadf2f4911ba9ffa600610003b4
The uuid is 2f234454-cf6d-4a0f-adf2-f4911ba9ffa6 and you can clearly see that in the payload. The Minor is 3 and the major is 977. What am I missing here??
d_in=bluetooth.resolve_adv_data(adv.data, Bluetooth.ADV_MANUFACTURER_DATA) if d_in: print(ubinascii.hexlify(d_in))
Many thanks, implementing that now, will get back to you

When you divide the manufacturer_data into fields, you will see the other data. I prepared some lines as follows.
d_in = bt.resolve_adv_data(adv.data, Bluetooth.ADV_MANUFACTURER_DATA) manuf_data = ubinascii.hexlify(d_in[0:4]) if manuf_data == b'4c000215': uuid = ubinascii.hexlify(d_in[4:20]) major = ubinascii.hexlify(d_in[20:22]) minor = ubinascii.hexlify(d_in[22:24]) tx_power = ubinascii.hexlify(d_in[24:25]) tx_power_real = twoscmp(int(tx_power, 16)) major_int = int(major, 16) minor_int = int(minor,16) print(read_adv,manuf,manuf_data, uuid, major, minor, tx_power_real, major_int)
Can you try this code?
Also, you can use this function for 2's complement.
def twoscmp(value): if value > 128: value = value - 256 return value
