ANT-multiple channels

[goran]

Hello,

Is there an example how to setup multiple ANT receive channels on one nrf51422 device using s310?

Thanks

I am trying to do this, but when I try to assign the second channel I get INVALID_PARAMETER (0x4033) back.

Here's a test I did to assign two independent channels on network 0.

uint32 err_code;
err_code = sd_ant_channel_assign(0, 0, 0, 0);
APP_ERROR_CHECK(err_code); //Success

err_code = sd_ant_channel_assign(1, 0, 0, 0);
APP_ERROR_CHECK(err_code);  //Fail here

My intention is to call the other initializations later but even if I do call the initializations for channel 0 first, the second one fails.

Edit: I am using SD s310 v3.0.0

Likely you need to alter 'ANT_CONFIG_TOTAL_CHANNELS_ALLOCATED' in:

uint32_t ant_stack_static_config(void)
{
    ASSERT(ANT_CONFIG_TOTAL_CHANNELS_ALLOCATED <= MAX_ANT_CHANNELS);
    ASSERT(ANT_CONFIG_ENCRYPTED_CHANNELS <= ANT_CONFIG_TOTAL_CHANNELS_ALLOCATED);

    ANT_ENABLE m_ant_enable_cfg =
    {
        .ucTotalNumberOfChannels        = ANT_CONFIG_TOTAL_CHANNELS_ALLOCATED,
        .ucNumberOfEncryptedChannels    = ANT_CONFIG_ENCRYPTED_CHANNELS,
        .pucMemoryBlockStartLocation    = ant_stack_buffer.u8,
        .usMemoryBlockByteSize          = ANT_BUFFER_SIZE_FOR_SD
    };

    return sd_ant_enable(&m_ant_enable_cfg);
}
