GATTC UUID128 example

Postby energia » Fri May 07, 2021 1:38 pm

Hello,

unfortunately I couldn't find any (up to date, ESP-IDF v4.2.x) example for GATTC UUID128 connections. Being still not really familiar with BLE after hours of studying it isn't that easy to adapt the gattc_demo provided.

I'm wondering if a different approach would work. I have to connect to a certain BLE address. Is it possible to use esp_ble_gattc_open() without prior scan? I would need to send a command to a handle and read the answer from another handle.

Thanks in advance.

I already saw this posting. However it's for Server, not Client.

Thank you. I will have a closer look at the code.
