ESP32 Forum

static assertion failed with "please enable bluetooth in menuconfig to use bt.h".

I get this error when I try to build bluetooth spp server demo.
my sdkconfig.defaults is as follows;
# Override some defaults so BT stack is enabled
# in this example

#
# BT config
#
CONFIG_BT_ENABLED=y
CONFIG_BTDM_CTRL_MODE_BLE_ONLY=y
CONFIG_BTDM_CTRL_MODE_BR_EDR_ONLY=n
CONFIG_BTDM_CTRL_MODE_BTDM=n
#
# ESP32-specific config
#
CONFIG_ESP32_ENABLE_STACK_BT=y
# CONFIG_ESP32_ENABLE_STACK_NONE is not set
CONFIG_MEMMAP_BT=y

Any help will be highly appreciated.

my problem was with setting the target .Case closed.

What do you mean by 'set target'?

@Senal Chandrasekara I think @nouwon means to run this command:
I'm having a similar issue with the esp32s2 development board. I was able to set the target successfully with "idf.py set-target esp32s2"

I then tried to enable bluetooth in my sdkconfig using the config menu (idf.py menuconfig). But none of the bluetooth options were enabled. I had to use the "[A] Toggle show-all mode" to even see the bluetooth options. Any idea why these may be disabled? Is the esp32s2 dev board not compatible with this sdk?

Your issue probably is that the ESP32S2 hardware does not support Bluetooth at all; it's a WiFi-only chip.
