I encountered an issue, please kindly refer to the attachment for the detail.
"''
The problem is:
a> Run demo on PCA10056 (BLE adv & ANT continuous scan).
b> ANT Dongle B broadcasts messages.
c> ANT Dongle A scans and sends acknowledged msg to B.
d> BLE advertising interval changes from 187ms to 1933ms automatically. (monitored by 'nrf Connect' App)
e> To recover the BLE advertising, the only way is resetting ANT stack by calling sd_ant_stack_reset().
f> ANT background scan mode wouldn't cause this problem.
The probability of this problem is 100%.

So I guess maybe there is something wrong in the ANT & BLE co-existed Softdevice, such as S340 and S332.
Can someone help me? Thank you in advance.
