ant scan can't found any device

[nanty]

Hi 

I'm encountering a problem than the ANT device cannot be scanned. you can use project "ble_ant_app_hrm_v324"(ncs 324）, and modify "

light_rx_open_head" to connect to your ant device, you will see the error "0x4015", and ant device cannot be scanned anymore. And, I use that project "ble_ant_app_hrm_v292" run with ncs 292（test code is same with "ble_ant_app_hrm_v324"）, it does't report error.

Plase help me solve this issue. Thanks.

Hello,

If I remember correctly ant_channel_open() return 0x4015 means channel is in wrong state.

Are you sure the channel is in closed state? E.g. wait for EVENT_CHANNEL_CLOSED before you open it again. When the issue occurs, what does sd_ant_channel_status_get() return?

Hi，

This issue occur then I do  ant_channel_close and can't get EVENT_CHANNEL_CLOSED response. And ant_channel_status_get() always is 2.

Can you wait for a long period of time for test? E.g. 40seconds? I think default search time is around 30 seconds, I just want to understand if it closes at the end.

Hi Kenneth,

 I have confirmed that when I do ant_channel_close, I can't get EVENT_CHANNEL_CLOSED even if timeout 50s. I have added the test project and test log.
