Hi Express Team,
I am trying to use BLE as part of my project. I am getting error when i try to add bt support. Enabled Bluetooth in sdkconfig. I tried clean build and full rebuild but no use. I am not able to figure out what is missing.

CMakeLists.txt
idf_component_register(SRCS "ble.c"
INCLUDE_DIRS "include"
REQUIRES bt driver nvs_flash esp_event)

Error : fatal error: esp_nimble_hci.h: No such file or directory

I resolved the issue, error is throwing because of Host was selected as "Bluedroid - dual-mode" instead of "NimBLE - BLE only" under menuconfig.

I am getting this error, but have enabled the nimble hci controller in menuconfig. What else could be the issue? How does that mechanism work of tying the menuconfig to the sdkconfig? As far as I can tell the sdkconfig is also correct. The Nimble stuff is all enable.

I even located the file on my Mac's hard drive. It does exist and is in the nimble include folder.

What controls where files like that are found?
