is it possible to use bluetooth communication without softdevice

[Satheeshkumar]

i am using nrf51822. is it possible blutooth communication without softdevice. if possible, please explain me how. if not why. please help me any one.

thanks in advance.

In order to use bluetooth with nrf51822 you will need a Bluetooth stack implementation. This is provided from nordic by the SoftDevices. Using a SoftDevice is most likely the simplest way to get Bluetooth working with nrf51822.

It is possible to use other bluetooth implementations on the nrf51822. Some customers have made their own implementations which might be more tailored to their requirements. The information about the nrf51822 chip required to make such an implementation is available at the nordic semiconductor infocenter (infocenter.nordicsemi.com).

There are other open source implementations of Bluetooth stacks that support the nrf51822 chip as well see https://mynewt.apache.org/ and https://www.zephyrproject.org/ for more information.

Note that nordic qualifies the softdevices and if you use an open source softdevice or develop your own you will need to qualify the controller and host yourself.

Hi,

Yes, it is possible to use the nRF51822 for Bluetooth communication without using our softdevice (bluetooth stack). However, it is not possible to have bluetooth communication without some software implementing the actual bluetooth protocol.

I would recommend that you use our stack, or one of the open source projects that @freqmod mention. It is also possible to do simple Bluetooth advertising, by using the radio peripheral directly and the bluetooth access address. Connections and more advanced functionality of the bluetooth protocol does require much code to work, and is not something I would recommend doing.

Best regards,

Jørgen
