ble scan and wifi connection in the same time

Postby dhs2017 » Fri Dec 14, 2018 8:28 am

Hi, with the latest esp-idf, except the blufi example. Is it possible to perform gatt client scan and wifi connection in the same time?

If it's possilbe, any special setting is required? such as the option in menuconfig.

thanks.

Hi,
yes it is possible.
I am working with Kolban's C++ library, but that should not matter. Couple weeks ago ive been doing simple test wifi + ble. In my test i have very simple esp http server with page that is displaying how many ble devices has been discovered and i can change interval and window times on the fly, and ble scan. Very interesting is that i could start scan with time 0 (infinity) and interval == window and still i had no issue for about week running app.

Only settings ive been changed in menuconfig was SW coexistence set to wifi priority. This suits best for me.

thanks, do you have any temperature overheat issue? it's because I tried ble+wifi before, when I use my finger touch the metal shield, it's very "warm", I think around 60C.
