Thank a lot.

The question is solved.

Because i called that ant_hrm_disp_open(&m_ant_hrm) once and ant_hrm_disp_open(&m_ant_hrm) in ant_evt_handler, it caused that open a channel that is already open and searching.

It seems you are trying to open a channel that is already open and searching.

Sorry to ask, but have you double checked that the log info show that there are different channels here? For instance for HRM:

<info> ant_hrm: ANT HRM channel 0 init
<info> ant_hrm: ANT HRM channel 0 open

But for next channel:

<info> ant_bsc: ANT BSC channel 1 init
<info> ant_bsc: ANT BSC channel 1 open

And so on.

What is the Channel Status if you call sd_ant_channel_status_get()?

Ans. STATUS_SEARCHING_CHANNEL((uint8_t)0x02) ///< Indicates channel is active and in searching state.

What have you set ucTotalNumberOfChannels when calling sd_ant_enable()?

Ans. NRF_SDH_ANT_TOTAL_CHANNELS_ALLOCATED = 7

#define ANT_HRMRX_ANT_CHANNEL 0 /**< Default ANT Channel. */
#define ANT_HRMRX_DEVICE_NUMBER 0 /**< Device Number. */
#define ANT_HRMRX_TRANS_TYPE 0 /**< Transmission Type. */
#define ANTPLUS_NETWORK_NUMBER 0 /**< Network number. */

#define ANT_BPWRRX_ANT_CHANNEL 1 /**< Default ANT Channel. */
#define ANT_BPWRRX_DEVICE_NUMBER 0 /**< Device Number. */
#define ANT_BPWRRX_TRANS_TYPE 0 /**< Transmission Type. */

#define ANT_BSCRX_ANT_CHANNEL 2 /**< Default ANT Channel. */
#define ANT_BSCRX_DEVICE_NUMBER 0 /**< Device Number. */
#define ANT_BSCRX_TRANS_TYPE 0 /**< Transmission Type. */

ant_hrm_disp_open(&m_ant_hrm) that is returning 0x4015.

Hi, I think we are going a bit in circles here now.

To be able to help you, I need to know exactly which softdevice api call that return error code 0x4015 (NRF_ANT_ERROR_CHANNEL_IN_WRONG_STATE). So you will need to find which of the sd_ant_channel_assign(), sd_ant_broadcast_message_tx(), sd_ant_channel_open(), sd_ant_network_address_set(), sd_ant_channel_id_set(), sd_ant_channel_radio_freq_set(), or sd_ant_channel_period_set() that is returning 0x4015.

Once we know which api call that return NRF_ANT_ERROR_CHANNEL_IN_WRONG_STATE, then next step is to find what are the paramters used in the specific softdevice call, and compare with the parameters for the other channel that is configured.

I setup (hrm and bsc) have it's own unique:
@param[in] ucChannel is an unsigned char (1 octet) denoting the channel to assign/open.

I used SDK13.1 successful.

But, I used the SDK14.1 then the above error situation happened.

Have you tried to look into my question:

In specific I suggest to check that each channel you setup (hrm and bsc) have it's own unique:
@param[in] ucChannel is an unsigned char (1 octet) denoting the channel to assign/open.

If several channel use the same ucChannel, then you very likely will get 0x4015.

Sorry, i modified my question.

If i opened ant hrm disp channel, i did not send bsc packet.
Then success.

And, if i opened ant bsc disp channel, i send bsc packet.
Then success.

But, if i opened ant bsc disp channel, i did not send bsc packet.

A period of time later.

Then return error code that 0x4015.

Hi,

I suggest you try to set some breakpoints or debug output in your code to find exactly which softdevice api call that return error code 0x4015 (NRF_ANT_ERROR_CHANNEL_IN_WRONG_STATE).

It may be that you are trying to assign or open a channel that is already configured. In specific I suggest to check that each channel you setup have it's own unique:
@param[in] ucChannel is an unsigned char (1 octet) denoting the channel to assign/open.

Best regards,
Kenneth
