Well, I will have to look further on this.

Thank you anyway for trying to help. It is much appreciated.

I don't see anything obvious here, so currently I don't have any good alternatives for debugging. Would just get back to debugging both step by step side by side to se what is going on.

Hi Jonathan,

thank you for your reply.

I am using sdk 17.0.2.

The issue occures here:

// Memory buffer provided in order to support channel configuration.
__ALIGN(4) static uint8_t m_ant_stack_buffer[NRF_SDH_ANT_BUF_SIZE];

static bool m_stack_is_enabled;

ret_code_t nrf_sdh_ant_enable(void)
{
    ANT_ENABLE ant_enable_cfg =
    {
        .ucTotalNumberOfChannels     = NRF_SDH_ANT_TOTAL_CHANNELS_ALLOCATED,
        .ucNumberOfEncryptedChannels = NRF_SDH_ANT_ENCRYPTED_CHANNELS,
        .usNumberOfEvents            = NRF_SDH_ANT_EVENT_QUEUE_SIZE,
        .pucMemoryBlockStartLocation = m_ant_stack_buffer,
        .usMemoryBlockByteSize       = sizeof(m_ant_stack_buffer),
    };


// memset(m_ant_stack_buffer,0x00,sizeof(m_ant_stack_buffer)); // test only

    ret_code_t ret_code = sd_ant_enable(&ant_enable_cfg); // returns 1
    if (ret_code == NRF_SUCCESS)
    {
        m_stack_is_enabled = true;
    }
    else
    {
        NRF_LOG_ERROR("sd_ant_enable() returned %s.", nrf_strerror_get(ret_code));
    }

    return ret_code;
}

With one project the call to "nrf_sdh_ant_enable" (nrf_sdh_ant.c) work fine the other returns an error.

In both cases I called nrf_sdh_enable_request() first.

I don't see any difference if using the memset or not.

sdk_config.h looks like that:

//==========================================================
// <e> NRF_SDH_ANT_ENABLED - nrf_sdh_ant - SoftDevice ANT event handler
//==========================================================
#ifndef NRF_SDH_ANT_ENABLED
#define NRF_SDH_ANT_ENABLED 1
#endif
// <h> ANT Channels 

//==========================================================
// <o> NRF_SDH_ANT_TOTAL_CHANNELS_ALLOCATED - Allocated ANT channels. 
#ifndef NRF_SDH_ANT_TOTAL_CHANNELS_ALLOCATED
#define NRF_SDH_ANT_TOTAL_CHANNELS_ALLOCATED 1
#endif

// <o> NRF_SDH_ANT_ENCRYPTED_CHANNELS - Encrypted ANT channels. 
#ifndef NRF_SDH_ANT_ENCRYPTED_CHANNELS
#define NRF_SDH_ANT_ENCRYPTED_CHANNELS 0
#endif


// <h> ANT Queues 

//==========================================================
// <o> NRF_SDH_ANT_EVENT_QUEUE_SIZE - Event queue size. 
#ifndef NRF_SDH_ANT_EVENT_QUEUE_SIZE
#define NRF_SDH_ANT_EVENT_QUEUE_SIZE 32
#endif

// <o> NRF_SDH_ANT_BURST_QUEUE_SIZE - ANT burst queue size. 
#ifndef NRF_SDH_ANT_BURST_QUEUE_SIZE
#define NRF_SDH_ANT_BURST_QUEUE_SIZE 128
#endif

Update:

For debugging try setting breakpoints when sd_ant_enable() is called and compare the working to not working application.

In addition using memset() first to check if it is in fact 0.

Jonathan

Hi,

This might be of help: https://devzone.nordicsemi.com/f/nordic-q-a/30859/how-to-expand-the-ant_config_total_channels_allocated-number

I am no expert on this but can you share some more info on the version of the SDK you are using?

And are you using the same HW ?

Looking in to this

Regards,
Jonathan
