Hello,
recently i made software for peripheral with custom service and five custom characteristics and everything works just fine. Now I want to make central capable of writing to my custom characteristics on perpiheral. I'm working with Central/Uart example from SDK. I changed example and now i can discover all my characteristics properly, but writing to them doesn't work. i'm using "ble_nus_string_send(&m_nus, data, sizeof(data))" but I'm not receiving anything on peripheral when I use discovered characteristics handles. What is strange when I use handle value 0x0003 I'm receiving event on peripheral, but only with this value. Can anyone tell what I'm doing wrong?
on_write handle on peripheral:
static void on_write(ble_config_t *p_config, ble_evt_t const *p_ble_evt)
{
ret_code_t err_code;
ble_config_evt_t evt;
ble_config_client_context_t *p_client;
ble_gatts_evt_write_t const *p_evt_write = &p_ble_evt->evt.gatts_evt.params.write;
err_code = blcm_link_ctx_get(p_config->p_link_ctx_storage,
p_ble_evt->evt.gatts_evt.conn_handle,
(void *)&p_client);
if (err_code != NRF_SUCCESS)
{
SEGGER_RTT_printf(0, "Link context for 0x%02X connection handle could not be fetched.",
p_ble_evt->evt.gatts_evt.conn_handle);
}
memset(&evt, 0, sizeof(ble_config_evt_t));
evt.p_config = p_config;
evt.conn_handle = p_ble_evt->evt.gatts_evt.conn_handle;
evt.p_link_ctx = p_client;
if ((p_evt_write->handle == p_config->rx_handlesID.value_handle) &&
(p_config->data_handler != NULL))
{
evt.type = BLE_CONFIG_EVT_RX_ID_DATA;
evt.params.rx_data.p_data = p_evt_write->data;
evt.params.rx_data.length = p_evt_write->len;
p_config->data_handler(&evt);
}
else if ((p_evt_write->handle == p_config->rx_handlesMeasurment_interval.value_handle) &&
(p_config->data_handler != NULL))
{
evt.params.rx_data.p_data = p_evt_write->data;
evt.params.rx_data.length = p_evt_write->len;
p_config->data_handler(&evt);
}
