Virtual Serial Port Wifi Adapter

These days, connecting your microcontroller project to a WiFi network is pretty easy — you connect up an ESP8266 to your microcontroller project and pretend it’s a WiFi modem, using these old-school-style AT commands. But what do you do if you need to flash new code into the microcontroller? You can’t reprogram the micro remotely through the ESP8266 because those stupid AT commands get in the way.The solution? By flashing the firmware into your ESP8266, you talk directly to the microcontroller over WiFi as if it were connected by a serial cable: the ESP8266 becomes a totally transparent WiFi-serial bridge. Now, with a serial bootloader and an ESP8266 in Wifi-to-serial bridge mode, you can reflash your microcontroller wirelessly, and then telnet in to interact with and debug the system remotely.

Once you’ve fixed the bugs, you can re-flash the microcontroller: all over WiFi, without having to climb up a ladder to reach your IoT attic-temperature sensor.To flash a connected Arduino, for instance, all you need to do is convince AVRDUDE to use the network instead of a locally-connected USB-serial cable: avrdude -p m328p -c arduino -b 115200 -P net:192.168.1.123:23 -U:yourHexFile.hex. The ESP8266 passes the data straight through its TX and RX lines to your microcontroller and everything works as if it were wired.Configuration to allow the ESP8266 to join your WiFi network takes place on a self-hosted webpage that uses Spritetm’s, which makes setup pretty painless.

And then after that you can simply telnet to the ESP8266 at port 23 and type away, or do anything else you would with a wired serial connection.Although the simple bridge mode came first, esp-link looks like it’s growing to be a one-stop shop for all your IoT or microcontroller + WiFi needs. In addition to the serial bridge code, there is also a REST-based microcontroller-to-internet mode and there is bi-directional MQTT support in the wings. We haven’t had a chance to dig into these yet, so if you have, let us know in the comments.If you want to dig in deeper, head over to for a slightly outdated tour of the project written by the code’s author, Thorsten von Eicken. For the most up-to-date development news, follow the very active development of esp-link in.Posted in, Tagged, Post navigation. Only 1 ADC, no hardware i2c, greatly reduced PWM, no 2-wirethe list goes on and on. My current project is a WiFi 3d printer controller which is why I’m so interested in the Pro Mini/ESP8826 combo (it’s what I’m currently using myself); the ESP8826 wouldn’t have the GPIO/ADC pins let alone support for any of the low-level hardware code in Teacup.

It’s a much more powerful chip, as you say, but it was built for a specific application and it’ll take time for many of existing libraries to be ported. A Pro-Mini/ESP8266 combo, on the other hand, is doable right now and would require nothing more than a PCB design. Don’ make it look like you are running a charity, You have ads setup on esp8266.com and so you do get ad revenue from running that site and putting a useless comment on every HAD thread about esp8266 linking to your site is your way of promoting your site.The discussion link that you had put in your comment was already given in the main article, So what was your point of putting it again? I doubt you even read main post completely before proceeding with your regular ritual of putting a comment on every esp8266 hackaday post.

There is what’s called “modem sleep”, which uses the Wifi DTIM interval (supported by almost all APs) to turn the receiver off for several beacon intervals (100ms) at a time. While the esp is in that mode, it uses 20mA. When the receiver is on it uses 70mA. Going down to 1-2mA requires turning the processor off, i.e., really just keeping memory and a timer powered and so far I’ve been unable to get into that mode. I believe that as long as there’s a peripheral enabled (such as UART) it can’t go into that mode ’cause there’s nothing to react to any input on the peripheral.

Wireless Serial Adapter for Wireless Networking. Enables access to remote devices while minimizing costly cabling. Provides network mobility for untethered communication. Industry standard 802.11b/802.11g wireless interface. Transparent communications – no need to develop special software. Two DB9 DTE serial ports supporting RS-232, RS-422 or RS-485 communication. Bulletproof wireless security with IEEE 802.11i-PSK,WPA-PSK, TKIP.

256-bit AES – end-to-end encryption. Ethernet or wireless communication.

Features TruPort® Com port control technology. Wirelessly Connect, Monitor, Manage and Control Devices Over a Network or the InternetWiBox dual port device servers enable you to connect equipment to 802.11b/g wireless networks via serial or Ethernet, quickly and easily. By merging wireless communications and Lantronix device server technology, WiBox simplifies connectivity to devices in applications where mobility is required or cabling is impractical.Lantronix’s innovative approach to network-enabling devices is transparent to your attached devices and software. You won’t need to change the way you work, and there’s no need to develop special software to take advantage of wireless networking capabilities. The WiBox simply becomes a conduit between you and your device over your network or the Internet.The flexibility and power of WiBox offers a huge cost-saving potential for a variety of commercial applications. Serial RS- 232/422/485 flexibility, Advanced security, robust data handling capabilities and high serial speeds are all built in.

Using a method called serial tunneling, the WiBox encapsulates serial data into packets and transports it over 802.11b/g wireless networks. By connecting two WiBox units via a network, virtual serial connections can be extended across your facility or around the world.The Com Port Redirector software included with your WiBox simplifies your integration process by extending the functionality of your COM port-based Windows® applications. With virtual COM ports mapped to remote device servers on the network, you can replace direct serial connections.To enable access to a local network or the Internet, the WiBox integrates a fully developed TCP/IP network stack and OS. It even includes a built-in web server, which can be used for configuration or to display operating and troubleshooting information on the attached links to online support.The DeviceInstaller configuration software that’s included simplifies installation and setup. WiBox can be set up locally through its serial port, or remotely over a network using DeviceInstaller Telnet or a web browser.

Flash memory provides maintenance-free, non-volatile storage of web pages, and allows future system software upgrades.In modem emulation mode, WiBox is used to replace dial-up modems. The unit accepts modem AT commands on the serial port, then establishes a network connection to the end device, leveraging wireless mobility and bandwidth to eliminate dedicated modems and phone lines.If you’re looking for a transparent, cost-effective and scalable means to network-enable your serial devices, look no further than WiBox from Lantronix. Total Com Port Control with TruPort TechnologyBuilt into the included Com Port Redirector software, TruPort® technology enables Windows-based applications to access and control serial ports on the WiBox as if they were actually local PC serial ports. The application can monitor and set hardware pins on the WiBox serial ports as well as access serial buffers for total Com port control. This allows existing applications to seamlessly transition from controlling local devices to true remote monitoring and control of devices around the world.
