I just added a for-loop after the err_code = sd_ant_channel_close(ANT_HRMRX_ANT_CHANNEL); that counted to 6000 and that was it. I don't want to share it as it's not the way to go, but it was a way to figure out what went wrong. You should follow testy's recommendations above here and wait for the EVENT_CHANNEL_CLOSED.

Hi Asbjørn : Could you please give me your example ?It can help me to pick out the wrong on my process.

You should wait, stack will send EVENT_CHANNEL_CLOSED afterwards. Return code 0x00 is just NRF_SUCCESS and indicates, that sd_ant_channel_close command has been succeeded.

how to know channel is closed or not? I get error code from "sd_ant_channel_close" is 0x00.

#define NRF_ANT_ERROR_CHANNEL_IN_WRONG_STATE          NRF_ANT_ERROR_OFFSET + CHANNEL_IN_WRONG_STATE  ///< Response on attempt to perform an action from the wrong channel state.

It seems like you haven't closed the channel you are trying to re-configure. Make sure that the channel is closed before you modify the parameters.

edit: You have do add a delay to ensure that the channel is closed before you change any parameters on it. I tested the routine you sent me here and it works, but it needs a delay. I did a nasty little for-loop to add a delay quickly, I would recommend you to wait for the callback and make sure that the channel is closed correctly before you change the device number and you should be fine.

I get some date from app_error_handler() .

error code: 0x4015

and error line is at:

err_code = sd_ant_channel_assign(ANT_HRMRX_ANT_CHANNEL, ANT_HRMRX_CHANNEL_TYPE, ANTPLUS_NETWORK_NUMBER, ANT_HRMRX_EXT_ASSIGN);

APP_ERROR_CHECK(err_code); // <------ error is at this line

What error code do you get? In main there are assert callbacks and app_error_handler that will display the error code and on which line it went wrong. Would also encourage you to try and step through the code with the debugger to see on which line it goes wrong.
