Return error code that 0x4015.

[Woody Hung]

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,
Kenneth

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.

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.
