Description: The RN-XV module by Roving Networks is a certified Wi-Fi solution especially designed for customer who want to migrate their existing 802.15.4 architecture to a standard TCP/IP based platform without having to redesign their existing hardware. In other words, if your project is set up for XBee and you want to move it to a standard WiFi network, you can drop this in the same socket without any other new hardware.
The RN-XV module is based upon Roving Networks' robust RN-171 Wi-Fi module and incorporates 802.11 b/g radio, 32 bit processor, TCP/IP stack, real-time clock, crypto accelerator, power management unit and analog sensor interface.The module is pre-loaded with Roving firmware to simplify integration and minimize development time of your application. In the simplest configuration, the hardware only requires four connections (PWR, TX, RX and GND) to create a wireless data connection.
Based on 3 ratings:
If you’re trying to replace an XBee-based solution - or you already have all of the XBee support hardware you want - this is a pretty solid option.
It is not 5V tolerant, and the sensor lines are only rated for 1.5V, so it’s not necessarily trivial to add this in to an existing project.
The onboard configuration options are great - the v4 firmware is possibly useful without another microcontroller for certain logging applications. Getting it on to local WiFi is pretty easy.
There’s no SSL/HTTPS support and I can’t find a firmware SDK.
Client mode worked really well, but using it as a server suffered from a few issues - sockets had to time out to close, drastically lowering throughput.
Best WI FI they cover all my needs thanks
I was astounded at the quality of this module for how cheap it is. The documentation is flawless, and I had no issues setting this up for my exact needs. It also performed incredibly well, even in a noisy PLC lab at my school where I was doing an industry project my robot was able to drive out the door, down the hallway, and into the grounds. If you need a cheap easy to use wifi module that will perform well, you can’t do much better than this
