https://devzone.nordicsemi.com/f/nordic-q-a/6343/ant-reset-pairing-bit-on-masterI am working on a system where two nRF51 will communicate with use of the ANT protocol (S210). The master and slave must be paired after pressing a button on both sides. I want to use the pairing bit of the Device Type, so the slave knows to which masteren-USTelligent Community 13Thu, 02 Apr 2015 13:26:15 GMThttps://devzone.nordicsemi.com/thread/22117?ContentTypeID=1Thu, 02 Apr 2015 13:26:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3bd9fc8e-dde1-414b-ad82-2afac3136b28RobK<p>According to <a href="https://devzone.nordicsemi.com/question/19078/changing-channel-id-while-in-event_tx-state/">devzone.nordicsemi.com/.../</a> and <a href="https://devzone.nordicsemi.com/question/18999/how-to-change-new-device_number-when-ant-device-is-working/">devzone.nordicsemi.com/.../</a>, the parameters for an ANT channel can only be changed when the channel is closed. But i&#39;ve tried to reconfigure an open channel and it seems you are right, it just works.
