ANT Forum

Hello,

I am using the Nordic 52833 and based on the nrf5SDK S332, running an application that supports the coexistence of BLE and ANT+. The BLE part includes 3 connections, acting as both a central and a peripheral. As a central, it has 2 connections with 45ms connect interval ; as a peripheral, it has 1 connection with 15ms connect interval. Meanwhile, it also connects to an ANT+ heart rate monitor.

The issue I am encountering is that after running for a while, there is a certain probability that the ANT+ connection will disconnect, softdevice reports the RX_FAIL_GO_TO_SEARCH event. I have tried using sd_ant_coex_config_set to configure it, but the effect is not ideal. Could you please suggest some solutions to reduce the probability of ANT+ disconnection? How to configure "slave latency" in the ANT protocol?

Thank you.      

I understand the complexity of working with multiple BLE and ANT+ connections at the same time, and getting RX_FAIL_GO_TO_SEARCH errors can be frustrating – hopefully you'll find a way to optimize your configuration to reduce interruptions, and I think further experimentation with Sprunki connection intervals or channel prioritization might help.
