Incomplete Advertising packet

[bbakerzzz]

Hello all Thanks for all the help in advance.

I am kind of new to micropython

My question/issue is when I use the LightBlue app on my phone I can see the following advertisement packet.
'''0201061AFF4C000215FDA50693A4E24FB1AFCFC6EB0764782500010002D80809616C6C77696E7311160318D0D5E036CE29000100020603E81B0000000000'''

When I use the following code snippet
'''def handle_scan(ev, data):
addr_type, addr, adv_type, rssi, adv_data = data
addr = hexlify(addr, ":").decode()
adv_data = hexlify(adv_data, ":").decode()
print(addr, adv_data)'''
I get
'''02:01:06:1a:ff:4c:00:02:15:fd:a5:06:93:a4:e2:4f:b1:af:cf:c6:eb:07:64:78:25:00:01:00:02:d8'''
Which match the begining of the packet.
'''0201061AFF4C000215FDA50693A4E24FB1AFCFC6EB0764782500010002D8'''

Which seems to be only part of the packet. What do I need to do to change this behavior?

I am using the following setup
ESP32-wroom-32u
1.19.1 of micropython
The sending device is an Allwins Ibeacon

Again thanks for the help

You may need to enable active scanning (See docs for gap_scan) and then the rest of the data might come in the active scan response.

[bbakerzzz]

I should have include how I start the scan.
'''
BLE().active(True)
BLE().irq(handle_scan)
BLE().gap_scan(60000, 55_000, 25_250) '''

Thanks but I did try that unless I have implemented the call incorrectly. Any input would be greatly appreciated.

See the active argument to gap_scan https://docs.micropython.org/en/latest/library/bluetooth.html#observer-role-scanner

Scanning is passive by default. If you enable active scanning, it will ask each device for it's "scan response" data, which enables an additional 31 bytes of data to be received.

Thanks for the information

When I use the following call.
'''BLE().gap_scan(20000, 55_000, 25_250, active='True')'''
I get the following error.
'''TypeError: function doesn't take keyword arguments'''

Do you know what I am doing wrong?

[bbakerzzz]

I have also tried without the quotes.

[bbakerzzz]

Never mind switched to and it is giving me more information.
'''BLE().gap_scan(20000, 55_000, 25_250, 1)'''

Again thanks for the information

If you use aioble it will join these up for you.

[jimmo]

(The advertising payloads and the scan responses, that is)

[bbakerzzz]

Thanks for the answer

Not sure what you mean here can you point me to an example?
I will also research on my own.

@bbakerzzz i recommend to use aioble module like @jimmo mentioned.

[straga]

How about BLE scan and WiFi sta - at the same time? For example scan BLE after sending to MQTT result.

[jimmo]

@straga Yes this should work.
