看门狗复位,IO口电平问题。
我抓了看门狗复位后IO的扣的电平,时序图到我IO初始化为上拉的电平之前有一段2.7S的低电平,前面这端低电平是低电平还是高阻态?

Hi,
I am completely new to da14580 programming.
I wish to establish a ble connection between my android device and da14580 basic kit.
Here's how i wish to achieve this:
1) The da14580 starts scanning for nearby devices.
2) After identifing the baddr of the android device it sends a pairing requests to the phone.
3) The pairing is completed using passkey.
Q1) Where do need to specify the baddr it needs to connect to?
Q2) What are things to be kept in mind while making an automatic connection?
Hi Dialog
I am working in DSPS_HOST project , when i tried to use breakpoint inside sps_client.c / sps_client_task.c compiler is not stopping , also i used
/****************************UART PRINT FUCNTION***************************************/
uart_init(UART_BAUDRATE_115K2,3);
uart_flow_off();
uint8_t something2[] = {"user_sps_enable\n"} ;
uart_write((uint8_t *)something2,sizeof(something2),NULL);
uart_finish_transfers();
Hi Dialog:
我需要在芯片运行的时候修改广播名字等参数,修改的app_adv_func()函数代码如下,
memcpy(&device_name_temp_buf[0],”ABCDEFG”, 7); //修改缓存
if(device_name_length > 0 || new_name_len >0)
{
// Check available space
device_name_length = co_min(device_name_length, device_name_avail_space);
使用的版本是5.0.4 ,我在工程里面定义了CFG_INITIALIZE_NVDS_STRUCT,我烧写nvds的只烧写蓝牙地址,怎么配置参数呢,谢谢,我测试了一次,烧写之后启动不起来,烧废了!
您好,我想咨询一下,我用DA14582同STM32通讯,采用了官方的串口驱动demo,然后在主函数调用串口接收接口,代码如下所示:
int main_func(void)
{
while(1)
{
#ifdef UART2_FUNCTION
uart2_read(UART2_RX_BUFF,1,UART2_CALLBACK);
#endif
}
}
其中UART2_CALLBACK函数中只调用 uart2_write(UART2_RX_BUFF,1,NULL);
但我发现如果STM32发送数据包超过15byte,DA14582串口接收的数据超过15byte的部分会丢失,且概率性发生
看了一下官方的串口驱动,暂时未发现其他问题,请问这是什么原因呢?
Hi Dialog,
How to measure DA14580 supply current using DEVKIT-B?
"AN-B-015", is it using expert?

hi ,
i have run the plt software both in win 7 and win 10 , some pictures show in the follow accessory.
please check the problem , and help me.
Hi,
We are using throughput_eval_peripheral example in our application. And we want to know what happens to the data packets that are added to the FIFO, if the receiver is not receiving the packets?
i.e. if the central device is out of range?
What happens once the central comes back to the peripheral range and at that time FIFO is full?
Will the data be lost?
Thanks

Hi All,
We''re curently developing a application based on the DSPS examples. Currently we are having trouble with the development of the iOS app. Is it possible to receive the source code of the DSPS app, as an reference for our developer?
Kind regards.
