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.
OverviewESP8266 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.

|Set the network mode||Check current mode||Return which modes supported||-|
- carefully there are must be no any spaces between the ' and IP address or port
Parameters and Examples
restart the module
check firmware version
1= Sta, 2= AP, 3=both, Sta is the default mode of router, AP is a normal mode for devices
join the AP
AT+ CWJAP =<ssid>,< pwd >
ssid = ssid, pwd = wifi password
list the AP
quit the AP
set the parameters of AP
AT+ CWSAP= <ssid>,<pwd>,<chl>, <ecn>
ssid, pwd, chl = channel, ecn = encryption; eg. Connect to your router: AT+CWJAP='www.electrodragon.com','helloworld'; and check if connected: AT+CWJAP?
check join devices' IP
get the connection status
<id>,<type>,<addr>,<port>,<tetype>= client or server mode
set up TCP or UDP connection
1)single connection (+CIPMUX=0) AT+CIPSTART= <type>,<addr>,<port>; 2) multiple connection (+CIPMUX=1) AT+CIPSTART= <id><type>,<addr>, <port>
id = 0-4, type = TCP/UDP, addr = IP address, port= port; eg. Connect to another TCP server, set multiple connection first: AT+CIPMUX=1; connect: AT+CIPSTART=4,'TCP','X1.X2.X3.X4',9999
set data transmission mode
0 not data mode, 1 data mode; return 'Link is builded'
1)single connection(+CIPMUX=0) AT+CIPSEND=<length>; 2) multiple connection (+CIPMUX=1) AT+CIPSEND= <id>,<length>
eg. send data: AT+CIPSEND=4,15 and then enter the data.
close TCP or UDP connection
AT+CIPCLOSE=<id> or AT+CIPCLOSE
Get IP address
set mutiple connection
0 for single connection 1 for multiple connection
set as server
AT+ CIPSERVER= <mode>[,<port> ]
mode 0 to close server mode, mode 1 to open; port = port; eg. turn on as a TCP server: AT+CIPSERVER=1,8888, check the self server IP address: AT+CIFSR=?
Set the server timeout
<time>0~28800 in second
For Single Connection mode(CIPMUX=0): + IPD, <len>:
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.
