How to use nrf52840 dongle like a BLE dongle to send data from Raspberry Pi 3B to another Bluetooth device?

[Lionel Tran]

I am new and trying to install and run samples on Raspi 3B but cannot. Have anyone worked with Raspi 3B and nrf52840 dongle and please give me some instructions.

Hi,

If you want to use the nRF52840 dongle as a standard BLE controller, you can use the HCI implementation found in Zephyr. Nordic does not provide any standard HCI apart from this.

You can also use the pc-ble-driver to write custom applications. There are Python and Node.JS versions available, but you will have to build these from source to make them support Raspberry Pi.

Best regards,
Jørgen

Hi, Thank for your answer

I built Zephyr with Raspi 3B to use nrf52840 dongle like a BLE dongle. First, I wanna run hello_world sample.

- Everything was okie when I ran: 

cmake -DBOARD=nrf52840_pca10059 .. 

(Question: is nrf52840_pca10059 right in this situation?)

- After that, I ran:

make

But issue occured:

/home/pi/zephyr/ext/hal/cmsis/Include/core_cm4.h:105:8: error: #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"

       #error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"

How can I solve this problem?

Best regards,

Lionel
