GATT Transactions examples

Hi all,

I am building a windows application for pokitmeter using Python, PyQT5 and bleak (by hbldh).

What I've done so far:

   1. Mock-up for the UI

   2. Connect with the device and change the device name using GATT transaction.

I aim to finish the project this year and I am still new to GATT and BLE. I'm having problem configuring the device on DMM mode. I can't even set it to Temperature measurement, please see the GATT transaction I've used below:

GATT Transaction for setting Temp Measurement
-----------------------------------------------------------------
write characteristic:     uuid:   "53dc9a7a-bc19-4280-b76b-002d0e23b078"
                                    value:   "\x08\x00\x00\x00\x00\x00" #set temp: option #8

read characteristic:     uuid:               "047d3559-8bee-423a-b229-4417fa603b90"
                                   read_value:    "006f93d2410800"      # hexadecimal 7 bytes
                                   read_gatt_descriptor_value:           "\x00\x00"      # zero temp reading?

What I need to continue:

    1.  Example GATT transactions, at least one for each mode (DMM, Scope, Logger). For scope, the       GATT example for fetching the waveform would be ideal.

    2.   Byte mapping for the DMM settings, it is said in the manual 6 bytes ( I've jut assume that the first byte is used for setting the Temperature acquisition).  A tabular byte mapping for each configuration will be handy.

    3.   Example of byte parsing of result to reveal human readable values

Thank you in advance!

Cheers,

jdon
