GAZELLE_ERROR_CODE_CHECK

[panduro]

when I call nrf_gzll_add_packet_to_tx_fifo after I recive a nrf_gzll_host_rx_data_ready() I get a Error 33542

how can I see what type of error that is?

I was hoping to get a nrf_gzll_error_code_t type, can I print it out or??

Hi,

 

33542 = 0x8300 + 6.

0x8300 is the gazell error base:

#define NRF_ERROR_GAZELLE_ERR_BASE          (0x8300)

 

That function adds the base to the error enum:

#define GAZELLE_ERROR_CODE_CHECK(GZLL_RESULT)                                       \
    do                                                                              \
    {                                                                               \
        if ((GZLL_RESULT) == false)                                                 \
        {                                                                           \
            nrf_gzll_error_code_t gzll_error_code = nrf_gzll_get_error_code();      \
            ret_code_t error_code = gzll_error_code + NRF_ERROR_GAZELLE_ERR_BASE;   \
            APP_ERROR_HANDLER(error_code);                                          \
        }                                                                           \
    } while (0)

 

The error is this one:

NRF_GZLL_ERROR_CODE_INVALID_PAYLOAD_LENGTH              =  6, ///< An invalid payload length was given as an input to a function.

 

This indicates that the length field has been corrupted (ie: > 32 byte, or equal to 0). Could you add a check on the length before adding to the TX FIFO?

  

Kind regards,

Håkon

great !! problem solved, just switched from STM32 to nRF, so still learning ..
