p_data_len and p_data will not be updated by the command request encoder. Updated values are set by ble_gatts_value_get_rsp_dec.
Return values
NRF_SUCCESSEncoding success.
NRF_ERROR_NULLEncoding failure. NULL pointer supplied.
NRF_ERROR_INVALID_LENGTHEncoding failure. Incorrect buffer length.

)

Decodes response to sd_ble_gatts_value_get command.

[in]packet_lenLength (in bytes) of response packet.
[out]pp_valuePointer to pointera buffer where the requested value will be stored.
[in,out]pp_value_lenin: Size (in bytes) of p_value buffer. out: Length of decoded contents of p_value.
[out]p_result_codeCommand result code.
Return values
NRF_SUCCESSDecoding success.
NRF_ERROR_NULLDecoding failure. NULL pointer supplied.
NRF_ERROR_INVALID_LENGTHDecoding failure. Incorrect buffer length.
NRF_ERROR_DATA_SIZELength of p_value is too small to hold decoded value from response.
