I used SDK nRF5_SDK_14.1.0_1dda907.
I added cycling speed and cadence service of BLE and bicycle speed and cadence of ANT+ in ble_ant_app_hrm example of multiprotocol.
If i opened ant hrm disp channel, i did not send bsc packet.
Then success.
But, if i opened ant bsc disp channel, i did not send bsc packet.
Then return error code that 0x4015.
How to solve it ?
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,

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.
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.
ant_hrm_disp_open(&m_ant_hrm) that is returning 0x4015.
What is the Channel Status if you call sd_ant_channel_status_get()?
What have you set ucTotalNumberOfChannels when calling sd_ant_enable()?
What is the Channel Status if you call sd_ant_channel_status_get()?
What have you set ucTotalNumberOfChannels when calling sd_ant_enable()?
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. */
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.
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.
