我正在使用DSPS来源code project , i am successfully reading data from a sensor , now i want to send this data through bluetooth and not through UART, to DSPS android app , how to do it , please mention the functions and steps

我正在使用DSPS来源code - sps_device project , i am successfully reading data from a sensor , now i want to send this data through bluetooth , to DSPS android app , how to do it , please mention the functions and steps

Q1。请提及用于将数据发送到DSPS应用的功能，
Q2 . also specify does DSPS source code API functions to send data through BLE and smartband IOT source code API functions are same

i am using user_send_ble_data(p_data , length) function in DSPS source code to send the data to DSPS app , is there any other function available to send data over BLE to DSPS

// extern void read_sensor(void) // MY REQ
// extern unsigned char SensorData[20]; // MY REQ

void user_ble_pull (bool init, bool success)
{
bool send_flow_on = false;
静态bool tx_busy_flag = false;
static uint8_t rounds_waiting=0;
static uint16_t length;

// read_sensor（）//我的req - 通过i2c从传感器读取

如果（init）
{
如果（！tx_busy_flag）
{
if((length = user_buffer_item_count(&periph_to_ble_buffer)) > 0)
if (length > TX_WAIT_LEVEL || (rounds_waiting++) >= TX_WAIT_ROUNDS)
{
uint8_t * p_data = null;

rounds_waiting = 0;
tx_busy_flag = true;

愣th = (length > TX_SIZE ? TX_SIZE : length);
长度=(长度< TX_START_FRAME_DATA_SIZE吗?愣th : (((length - TX_START_FRAME_DATA_SIZE) / TX_CONTINUE_FRAME_DATA_SIZE) * TX_CONTINUE_FRAME_DATA_SIZE + TX_START_FRAME_DATA_SIZE));
愣th = user_buffer_read_address(&periph_to_ble_buffer, &p_data, TX_SIZE);
p_data [0] ='p';
p_data [1] ='p';
p_data[2] = 'P';
p_data [3] ='a';

长度= 4;
user_send_ble_data（p_data，长度）;
// user_send_ble_data((const uint8_t *)SensorData, length); // MY REQ
}
}
}
else
{
tx_busy_flag = false;
if (success)
user_buffer_release_items(&periph_to_ble_buffer, length);

if（（length = user_buffer_item_count（＆periph_to_ble_buffer））> tx_wait_level）
{
uint8_t * p_data = null;

rounds_waiting = 0;
tx_busy_flag = true;

愣th = (length > TX_SIZE ? TX_SIZE : length);
愣th = (((length - TX_START_FRAME_DATA_SIZE) / TX_CONTINUE_FRAME_DATA_SIZE) * TX_CONTINUE_FRAME_DATA_SIZE + TX_START_FRAME_DATA_SIZE);
愣th = user_buffer_read_address(&periph_to_ble_buffer, &p_data, TX_SIZE);
p_data [0] = ' V ';
p_data[1] = 'V';
p_data [2] = ' V ';
p_data[3] = 'B' ;

长度= 4;
user_send_ble_data（p_data，长度）;
// user_send_ble_data((const uint8_t *)SensorData, length); // MY REQ
}
}
上面的代码工作正常，我在DSPA移动应用程序上获得一些数据，如果我启用//我的req注释，代码进入无限循环，我无法获得任何数据

以上代码，在i2c read_sensor（）中添加延迟会影响代码？，即使在IOT项目和I2C EEPROM中我也没有看到任何延迟......
谢谢你...

i have included timer0 interrupt for delay , this -- while (timeout_expiration); -- line in function void timer0_general_test(uint8_t times_seconds) makes the code infinite loop , what could be the issue , alone timer0 code working fine , inside the DSPS not working

你可以把这个票子打倒，我得到了答案，谢谢你的帮助......

hi GauravBansal
i am using tha AN-B-029_V1.0 for custom profile to read data and send via bluetooth , this rar extention has the tutorial pdf also..that would be helpful for u

Hi GauravBansal
I didn't understand your question - how to integrate my board to any sensor and also through the DSPS app??,
if you are working in BLE CLIENT - BLE SERVER , refer this link
