https://devzone.nordicsemi.com/f/nordic-q-a/44848/sdk-13-1-nrf52832-ant-channel-collisionDear Nordic ： Our mass-produced smart trainer( 16M external oscillator, 20PPM ) supports ANT+ FEC and ANT+ Bicycle Power , so there are two channels alive wtih 4Hz frequency in our firmware. We have been troubled for a long time about the signal interferenceen-USTelligent Community 13Thu, 14 Mar 2019 08:40:34 GMThttps://devzone.nordicsemi.com/thread/176097?ContentTypeID=1Thu, 14 Mar 2019 08:40:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5decf804-bd27-4777-b878-6025e912a19cKenneth<p>Hi,</p> <p>The channel period of ANT+ bicycle power is 8182 (/32768 seconds) and the channel period of ANT+ fitness equipment is 8192 (/32768 seconds). This means that intermittently over time they will collide in time, before the drift apart again. There is a difference in channel period of (8192-8182)/32768 seconds = 0.305ms, but since both transmit on average about every ~250ms, they will collide sometimes. There is nothing that can be done about this.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
