How to create service bin file .

[Karan_26]

Hi
By using AT commands, i'm able to read/write characteristics of only one predefined service .
i want to create a temperature service , I have created .csv file .

index uuid_len uuid perm val_max_len val_cur_len value
0 16 0x2800 0x01 2 2 A232
1 16 0x2803 0x01 1 1 2
2 16 0xC300 0x10 1 1 1
3 16 0x2901 0x11 512 1 1
4 16 0x2803 0x01 1 1 2
5 16 0xC301 0x01 512 512 ...
6 16 0x2901 0x11 512 512 ...

Now , i don't know how to create .bin file from .csv file , so that it can be downloaded into esp32 module .
I don't know how to use python to create bin file .
Please provide me some examples or steps so that i can create TempService.bin file .

Thank you for support .
service bin file has created successfully .
Actually xlrd and yaml had to be installed with python setup.

I have a question about ESP32 I am working with the esp32-at project
I want to change the services and characteristics of the BLE but I don't know how to do it.

I am currently compiling it from eclipse, but I don't know what library they are in or it has to be done with the ATBleService.bin

If so, where should I put this file to compile it with the project?
