Hello everyone!
I am trying to implement a free fall detector using the IOT sensor, I want the any motion detection to be replaced by the free fall detection interrupt.
I tried and tried but it keeps not working, and here is my code :
in user sensor.c :
void user_bmi160_config_low-g_intr( void ) {
bmi160_set_low_g_enable(BMI160_ENABLE);
bmi160_set_low_high_g_source(0x01);
Experimental Setup: I use Huawei smartphone for Central and DA14583 IoT sensor as peripheral. The software running on the smartphone is an app using Evothing framework. I would like to read acceleration and angular velocity at the same time to do the motion capture.
Sensor's firmaware: IoT raw project.
Sample rate for accelerometer and gyroscope: 50Hz.
The code on the central device using Evothing is as follows:
//Received data
app.handleSensorAccelerometer = function (data) {
data["time"] = Date.now();
Hi,,
I having problem connecting two devices.
Dev1 (slave) is sending advertisement containing data which I want to retrieve on Dev2 (Central).
Dev1 seems fine and sending regularily without any issue and its advertisement is reached on dev2 at call app_easy_gap_start_connection_to_set. I want to connect to the device and as I understand I call app_easy_gap_start_connection_to_set. And eventually after canceling the scanning the call app_easy_gap_start_connection_to is made.
Dear,
Maybe I missed a document and the things below can be ignored, but I think it would be helpful to have a document of setting up the toolchain and updates and the possible mixing of Keil and GCC tools.
So maybe I'm asking for things that are obvious...
我最近尝试使用最新版本安装工具/软件/ IDE，但是我有点困惑。上面有适当的升级/安装手册吗？
Hi All,
No question here just wanted to inform anybody else that is having the same issue as I did, since I already found a workaround.
The problem I had was that the flash was not correctly written to, even though I used the SPI_Flash example, without any changes made. Reading the flash only gave me zeros (everything was 0x00).
However when I made the following changes, it worked.
In spi_flash.c , the snippet below generates the error.
您好，
我使用你们发给我的，hex2bin工具，无论是windows7 平台 还是 ubuntu平台的 hex2bin 都无法生成正确的 bin文件。

Hi there,
Hi all!
My central must do 2 types of activity:
- scanning, communication and disconnection after transmitting data to device or in case of timeout. It must be done after request from my application.
- periodical activity (for example every 100ms) using timer(created by app_easy_timer).
Hi All,
Experimental Setup: I tested the Evothings viewer with the tablet Teclast-TPad X80H. The firmware that I used in IoT Sensor is 5.160.01.19.
Problems: I found a Connection error 133 when trying to connect the IOT sensor.
However, when I using Huawei, it works properly.
Questions: Could you please give me some hints why this happened and how to modify the code on the IoT sensor?
Best Regards,
Yufan
