Hi,
I have created my own hardware with nRF54L15 – 2xLED, 2xPWM, and Radio (BLE). I am trying to create a custom board using the graphical wizard.
LED and PWM seems to work – the project compiles, but I could not test it on hardware yet.
Now, I want to add BLE support - advertising and connection. How can I prepare my board in DeviceTree (DTS), or in the graphical wizard? Is there any step-by-step guide or tutorial for this?
Thank you very much for your help!
I found this gpio-radio-coex:
in prj.conf I added:
# BLE CONFIG_BT=y CONFIG_BT_DEVICE_NAME="ZGuard" CONFIG_BT_PERIPHERAL=y CONFIG_BT_EXT_ADV=y CONFIG_CLOCK_CONTROL_NRF=y # LFCLK: (32.768 kHz) CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y
this is in my defconfig ..._cpuapp_defconfig:
This is in my .dts:
this is my .overlay:
