Dear all,
I have been struggling with updating my advertisement data package in SDK15. Using Jimmy Wongs's example (https://github.com/jimmywong2003/nrf5-modify-device-parameter-through-host/blob/modify_non_connectable_advertising/ble_app_change_advertising_example/main.c) and after modifying it accordingly, I was able to get the result I wanted out of it.
The working part is the following:
static uint8_t m_enc_advdata[BLE_GAP_ADV_SET_DATA_SIZE_MAX] =
{
02, 0x01, 0x06, //flags
0x11, 0xFF, 0x59,
0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09,
0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09,
0x00, 0x01, 0x02, 0x03,
};
static uint8_t m_enc_rspdata[BLE_GAP_ADV_SET_DATA_SIZE_MAX] =
{
02, 0x01, 0x04, //flags
0x11, 0xFF, 0x59,
0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09,
0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09,
0x00, 0x01, 0x02, 0x03,
};
static ble_gap_adv_data_t m_adv_data =
{
.adv_data =
{
.p_data = m_enc_advdata,
.len = BLE_GAP_ADV_SET_DATA_SIZE_MAX
},
.scan_rsp_data =
{
.p_data = m_enc_rspdata,
.len = BLE_GAP_ADV_SET_DATA_SIZE_MAX
}
};
static void ble_stack_init(void)
{
ret_code_t err_code;
err_code = nrf_sdh_enable_request();
APP_ERROR_CHECK(err_code);
// Configure the BLE stack using the default settings.
// Fetch the start address of the application RAM.
uint32_t ram_start = 0;
err_code = nrf_sdh_ble_default_cfg_set(APP_BLE_CONN_CFG_TAG, &ram_start);
APP_ERROR_CHECK(err_code);
// Enable BLE stack.
err_code = nrf_sdh_ble_enable(&ram_start);
APP_ERROR_CHECK(err_code);
}
static void non_connectable_advertising_init(void)
{
uint32_t err_code;
m_adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;
m_adv_params.interval = NON_CONNECTABLE_ADV_INTERVAL;
m_adv_params.duration = APP_ADV_DURATION;
m_adv_data.adv_data.p_data = m_hardcode_enc_advdata;
m_adv_data.adv_data.len = 0x1F; // hardcode to 31 bytes
m_adv_data.scan_rsp_data.p_data = m_hardcode_enc_rspdata;
m_adv_data.scan_rsp_data.len = 0;
err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &m_adv_params);
APP_ERROR_CHECK(err_code);
}
int main(void)
{
uint32_t err_code = NRF_SUCCESS;
lfclk_config();
rtc_config();
saadc_init();
nrf_drv_saadc_sample();
measure_battery();
wdt_init();
gpio_init();
power_management_init();
ble_stack_init();
sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
sd_power_mode_set(NRF_POWER_MODE_LOWPWR);
non_connectable_advertising_init();
non_connect_advertising_start();
printf("Advdatasize %d\n", sizeof(m_hardcode_enc_advdata));
printf("Rspdatasize %d\n", sizeof(m_hardcode_enc_rspdata));
printf("My_tag tag started!\n");
// Enter main loop.
for (;;)
{
NRF_WDT->RR[0] = WDT_RR_RR_Reload;
measure_battery();
idle_state_handle();
NRF_WDT->RR[0] = WDT_RR_RR_Reload;
}
}
But things go wrong when I change the length of the response package to a non-0 value. By wrong I mean that when I have the debugger connected the code jumps to app_error_handler.gcc.c (line 49) and from there to app_error_weak.c (line 100). The error occurs on err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &m_adv_params);
And it is NRF_ERROR_INVALID_PARAM. But I am not sure which parameter is wrong. Or how is the correct configuration for that matter.
Any help/indication would be very helpful.
Thank you very much
