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

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

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
