https://devzone.nordicsemi.com/f/nordic-q-a/17000/nrf51822-bluetooth-and-gazell-enabled-at-same-timeHi Can we have both bluetooth and Gazell enabled at the same time? We are using nrf51 series chips. We want Gazell to communicate with with other nrf chips and Bluetooth to communicate with the phone.

Please start by reading this tutorial on <a href="https://devzone.nordicsemi.com/tutorials/16/">setting up the timeslot API</a>. We also have an <a href="https://devzone.nordicsemi.com/question/57794/example-of-using-the-concurrent-multiprotocol-timeslot-api-for-ble-gazell/">example on using gazell with BLE</a>, however it might be a little bit dated.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
