Reset UART (restart UART)

Reset UART has two methods: UART reset. Write 0 to the UART reset bit (urst) of the power and emulation control register, urpecr. This operation resets the UART state machine without affecting the UART registers. DSP reset. Reduce the reset # pin of the DSP. The entire

1_ble nrf51822 uart and ble forwarding

Last year, noridc developed a chip that integrates Bluetooth 4.0 and can communicate with 24l01. The film encapsulation can be very small, and the power consumption is very low. It is very suitable for wearable devices, so I recently had a set of second-hand ak ii and no becon board. I first played some basic peripherals, And now I started to develop ble. Under the official SDK directory, we can find the project file Nordic \ nrf51822 \ board \ pca100

Linux wireless network technology: Bluetooth

By Sreekrishnan Venkateswaran Linux Bluetooth Bluetooth is a short-range wireless technology used to replace cables. It supports 723 kbps (asymmetric) and 432 kbps (symmetric) speeds to transmit data and voice. The transmission range of a Bluetooth device is about 10 meters (30 feet ). BlueZ is the official Linux Bluetooth

Differences between bluetooth 1.1, Bluetooth 1.2, and Bluetooth 2.0 (Bluetooth 2.0 + EDR)

Bluetooth 1.2 vs 1.1: 1. Adaptive Frequency Hopping (AFH ):Adaptive Frequency Hopping TechnologyThe main function is to reduce interference problems between Bluetooth products and other wireless communication devices. 2. Extended synchronous connection-oriented links (ESCO ):Extended synchronous link-oriented channel technologyIt is used to provide audio transmission with high QoS, and can further meet the

Bcm4330 Bluetooth analysis summary

Bluetooth is implemented on the HCI Layer regardless of the underlying hardware driver. That is to say, the driver of HCI on the host is mainly to provide unified interfaces for the upper layer, so that the upper layer protocol does not depend on the specific hardware implementation. The firmware of HCI in the hardware communicates with the driver of HCI on the host, such as UART, USB, and SDIO. The HCI Lay

Basic UART knowledge

UART (Universal asynchronous transmitter ER/transmitter)General asynchronous transceiver UART is a chip used to control computers and serial devices. One thing to note is that it provides an interface to the RS-232C data terminal device so that the computer can communicate with the modem or other serial devices that use the RS-232C interface. As part of the interface,
