Issues related to the coexistence and interoperability of Bluetooth and ANT+ on the nRF52832 chip.

Hi, everyone

I am currently working on the development of Bluetooth and ANT+ on the nRF52832 chip. It communicates with my chip via UART, and now there are occasional disconnections of the heart rate sensor connected via ANT+. At present, I want to know the possible causes, such as the ANT+ search channel configuration, Bluetooth scanning parameters, Bluetooth connection parameters, Bluetooth advertising parameters, etc.

Hello,

I assume you are an ANT+ developer, so you can go to: https://www.thisisant.com/developer/components/nrf52832/#tab_tech_resources_tab 

Then for instance in the S332 SoftDevice Specification document you can find a table named Table 16-1. Scheduling priorities. 

If you are scanning in BLE and ANT, you likely want to reduce the priority and timing of those, such that they doesn't block the active ANT and BLE links for a long period of time.
