BLE-NRF51822 tutorial 8-dynamic Broadcast This topic describes how to implement dynamic broadcast. The tutorial is based on the Uart example in the 9.0 sdk. To implement dynamic broadcast, choose broadcast> stop broadcast> modify parameters> restart broadcast. Therefore, we use a timer to Periodically disable broadcast and then modify broadcast data before enabling broadcast. In Sdk 9.0, I implemented several broadcast modes, which was a little tro

Not only advertiser to be clear about which values this part should fill, but the scanner and initiator of interest will parse the values to make the necessary judgments.AD TypeThere are probably 30来 species, and for the sake of coding convenience, the SIG is assigned number for each ad type, which can be directly seen in the number a

[BLE--HID] usb hid device category definitionBrief Introduction HID devices are human-computer interaction devices. Common devices include the mouse, keyboard, and game handle. Generally, the wired connection is connected to the machine device through a USB connection, which serves as the user input device. In bluetooth technology, access to HID devices is wireless. However, the definition of HID is the same, or problems such as device drivers and com

DHT11 and DHT10 sensors, mainly collect temperature and humidity, based on my I2C simulation library implementation. The main code is as follows: #ifndef _sh10_drv_h_ #define _sh10_drv_h_ #include "stm32f10x_lib.h" void Sh_i2cinit (void); U8

We have accumulated this experience: if a large piece of data needs to be sent over TCP, we will adopt an Asynchronous Method to avoid blocking of the current Working thread. So, if we have multiple threads that need to send large pieces of data at

Android 4.3 (API level 18) has started to introduce the core features of Bluetooth low energy (BLE, Bluetooth) and provides APIs that enable applications to scan devices, query services, The characteristics (attribute feature) of the read-write device. Compared to traditional Bluetooth, BLE is designed to significantly reduce power consumption. This makes it possible for low-power communication between Andr

Abstract:The development of the signal processing circuit of the infrared focal plane array is introduced. The basic structure, working mode and application fields of CCD Multi-Channel transmitter (CCD-MUX), time delay integrated CCD (TDI-CCD), MOS and CMOS multi-channel transmitter (CMOS-MUX) are described. Finally, two application circuits of multichannel transmission devices are provided. Keywords:Signal
