I have done some further tests now by including the methods decode_services, decode_field, decode_name and the constants of the ADV_TYPES into my central device class directly I.e. not imported from ble_advertising. This is working now i.e. services for ADV_TYPE UUID128_MORE are no properly decoded....

I was able to track down further why the device I am looking for is not showing up as scan result with the standard ble_advertising helper on GitHub. My initial suspicion was actually right. The device advertises with ADV_TYPE 6 which means incomplete UUID128 list of services. The payload is as foll...

Hi,

You can find examples here:
https://github.com/micropython/micropy ... /bluetooth

Just for if anyone interested, the payload is structured as following (as stated in the ble_advertising example on GitHub: # 1 byte data length (N + 1) # 1 byte type (see constants below) # N bytes type-specific data So for the example payload 02,01,06,0c,09,6d,69,63,72,6f,70,79,74,68,6f,6e,03,03,1a...

I looked into the bluetooth spec more closely and it looks like the recorded payloads did not advertise any service. This is probably the reason why the services are empty. However, that leaves me the question why my own bluetooth peripheral (Arduino Nano BLE) is not discovered by the central ( ESP3...

I am using the BLE advertising helpers from GitHub in my central device scanning for peripherals. However, services for advertising packets that have UUID16 are decoded. For devices that have UUID128 services list are returned empty. In the code below first the example payload is generated and decod...

Sure you are right.

The reason why I posted it here was that I thought it was related to version and documentation differences.
I will start a new thread for the problem.

The constants seems to be correct after checking the bluetooth specification again. Nonetheless I am only returning empty services for the scanned devices except for the Corona warn characteristic of a nearby smartphone. [] [] [UUID16(0xfd6f)] [] [] [] [] [] [] Is there some possibility of logging i...

I have noticed that scan results only works for me for UUID16. Devices for with UUID32 or UUID128 are not detected. I suspect that is a similar problem with the IRQs. These constants are not correct for 1.12 are they? Advertising payloads are repeated packets of the following form: # 1 byte data len...

To enable notifications you need to set the "notifications enabled" bit on the CCCB descriptor. (This is what nRF Connect does when you toggle notifications). Thank you! How do find the value handle for the CCCB descriptor for a specific characteristic? Do I simply look for the 0X2902 UUID followin...
