128 bit custom service using gatts_data.csv

Postby jonathan.comley » Tue Jul 23, 2024 1:12 pm

HI kind people of this forum,

This is my setup:
ESP-AT Project: AT version:3.3.1.0
Bin version:v3.3.1.2-dev(MINI-1) ESP32C3

Can someone please advise if I am able configure a custom service 128bit UUID using the gatts_data.csv file.

I have tried many different combinations but seem unable to get it to work. Everything is working fine when using 16 bit UUID, I am able to connect and exchange data until the cows come home .

I am using this command for advertising the 16 bit UUID:

AT+BLEADVDATAEX="ESP-AT","3112","0102030405",1

Please advise what the gatts_data.csv and the advertising command should be to achieve my goal. Many thanks in advance.

This is my current gatts_data.csv files contents for the 16 bit UUID:
# index,uuid_len,uuid,perm,max_len,cur_len,value
0,16,0x2800,0x01,2,2,3112
1,16,0x2803,0x11,1,1,1b
2,16,0x3113,0x11,512,512,30
3,16,0x2902,0x11,512,512,0011
