试了一下gatt_server_service_table例程

虽然,可以收发数据,但是发送(手机端读取)只能是固定的

static const uint8_t char_value[4] = {0x11, 0x22, 0x33, 0x44};

如果需要可以手机正常收发通讯的,应该用哪个例程?

while(true)
{
if( gatts_info.bEnable )
{
i++ ;
buf[0] = i >> 24 ;
buf[1] = i >> 16 ;
buf[2] = i >> 8 ;
buf[3] = i ;
esp_err_t t = esp_ble_gatts_send_indicate(gatts_info.gatts_if , gatts_info.conn_id, gatts_info.attr_handle ,
sizeof(buf), buf, false);

ESP_LOGI(GATTS_TABLE_TAG,"send %d ,ret %d",i,t);
}
vTaskDelay(500);
}


已经可以发数据了,通过这个函数发数据。
