Qualcomm At Commands Pdf



I'm looking for commands to interact with an android device in EDL mode. There are different software which can interact with an EDL device, such as MiFlash and QFIL (Qualcomm Flash Image Loader). I searched for commands, fastboot like, but I found none. AirPrime EM74xx-MC74xx AT Command Reference Jan 31, 2019 - Author: Sierra Wireless - Version 4 - 41036 Views This document describes proprietary, password-protected AT commands available for Sierra Wireless AirPrime® 9x30-based intelligent embedded modules.

Overview

ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements.

Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.

ESP8266 on-board processing and storage capabilities allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. With its high degree of on-chip integration, which includes the antenna switch balun, power management converters, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Sophisticated system-level features include fast sleep/wake context switching for energy-efficient VoIP, adaptive radio biasing for low-power operation, advance signal processing, and spur cancellation and radio co-existence features for common cellular, Bluetooth, DDR, LVDS, LCD interference mitigation.

Upgrading ESP8266 Firmware

How to upgrade ESP8266 firmware?

We use NodeMCU flasher here, the download links:

  • English version: https://github.com/nodemcu/nodemcu-flasher

Note: use nodemcu flasher to flash Firmware to ESP8266, its default firmware is Lau language. If you want to flash AT Commands firmware, go to ESP8266 forum to get one.

  • Chinese version: File:ESP8266Flasher-x86-v0.9.2.3.zip

1. Connect your ESP8266 module as follows:

  • Vcc = 3.3V (needs around 300-400mA peak)
  • Gnd = -ve ground
  • CH_PD = Chip enable so always +ve
  • RST = Leave floating or ground to reset
  • GPIO0 = Normally floating but this needs to be grounded when you start the update.
  • GPIO2 = high level
  • UTXD = Tx data connect to RX on FTDI/Serial interface
  • URXD = Rx data connect to TX of FTDI/Serial interface

English Version: Please refer to the NodeMCU flasher user guide.

Chinese Version: Please see the next step below

2. Open the software, choose the right COM and click the button that is circled in the following picture. When a tick appears in the bottom-left corner, it suggests that the firmware upgrade successfully.
