does nrf52840 has ble 5. is it compatible with raspberry pi3?

[vidhi gupta]

hi ,

i am trying to make a project based on detection using ble 5 on raspberry pi 3.

plz help me with selecting correct and most appropriate ble 5 dongle for good range and fast speed.

"has BLE 5" is almost meaningless; so many BLE 5 features are optional - which particular BLE 5 features are you looking for?

devzone.nordicsemi.com/.../153430

The Product Specification tells you what BLE 5 features are supported.

What, exactly, do you mean by "compatible with raspberry pi3"

The nRF52840 has a number of interfaces which are available on the RPi3 - UART, USB, SPI, I2C.

The Raspberry Pi3 has a BCM43438 wireless LAN and Bluetooth Low Energy (BLE)  chip:

That is only BLE 4.1:

Hi

As Andrew says, the Raspberry Pi3 doesn't support BLE 5. But if you want BLE 5 USB Dongles based on the nRF52840 anyway, check out Fanstel, Raytac, and/or our own nRF52840 Dongle. Please note that our Dongle is not optimized for range, and is to be considered a development tool. I assume both Fanstel and Raytac probably have better optimized solutions for an actual product, although the Nordic Dongle will be easier to develop on.

Best regards,

Simon

But the actual development will be much easier on a Dev Kit!

But now we have the RaspberryPi 4:
