QN9080 BLE

i designed a pcb based QN9080,and download the temperature_sersor of wireless_examples. I changed the connection interval gcConnectionIntervalMinDefault_c to 800U, the gcConnectionIntervalMaxDefault_c to1600U, but It doesn't seem to work，and This is the current consumption diagram of BLE connection after modifying the connection interval

Hello @Kynnans

Let's check where the problem may be. Before modifying, can your device work fine?

i found the reason, i need to use the function Gap_UpdateConnectionParameters. but there is another RF event that occurs every 30ms , I don't know what this event is.

Hello @Kynnans

Can you share your code with us? Because I don't clear how do you call this API.
