Elm327 WiFi OBD2 Interface Can Bus Scanner Diagnostic Tool with Original 25k80 Chip Support iOS/Android V2.1

This is the wifi version. Get the bluetooth. Otherwise it works perfectly.

Was surprised to find how well it works.

This device works great, especially with the torque app

This arrived in a nondescript brown box that contained the device and a mini-compact disc. Does anyone still use those? My PCs don't have a disc drive like that, so the disc is worthless. Moving on...The ELM 327 module was plugged into my OBD2 port with ease. The red power light turned on and I started the car. I put my Android phone into airplane mode and then reactivated the wifi. I discovered the ELM 327's ad-hoc network and connected my phone without issue. I was able to determine the IP address of the device and used that to attempt connection with various scanner software applications.The current version of Android does not support Torque Lite. The app seems to be far out of date. There is a paid version available, of course. I tried eight other apps. I had no luck getting any of them to connect to the ELM reader. I may have the port identified incorrectly, but with no documentation or other sources of information from the product vendor, I cannot tell.The price is good, but being unable to connect makes the device useless at any price.

Compared to a Bluetooth reader this WiFi model is a bit more annoying to use on your everyday phone, not much in the way of documentation.To connect, use the following IP address and port:192.168.0.10:35000I like the torque app, but in case you use anything else and need to configure it you're to have a hard time woth knowing that IP/port combination. On the bright side, the flexibility is great. I love being able to use any app I want.What I don't like is having to turn off mobile data to force my phone to use the WiFi from this reader amd essentially losing all other functionality of my phone while monitoring my car's performance. It's almost a requirement to use a dedicated tablet or similar device as a reader.I tend to leave a wireless reader attached to my car at all times, so if anything gives me trouble I can immediately read the codes and monitor what's going on as I'm driving. This saved my car just the other day when out of the blue some road debris got sucked up into my undercarriage, snagged on a belt, and subsequently broke the belt driving my water pump. The coolant temp reading on the instrument cluster didn't change but thanks to being able to open up a full breakdown of all the temperatures in my engine in realtime, I was able to diagnose the fault and prevent catastrophic damage to my engine. I also drove the rest of the way home safely by monitoring the temperatures and using inducted air along with the oil cooler to dissipate the heat from short acceleration bursts.That device was Bluetooth. To do the same with this device, I would need to open several sub-menus and toggle off mobile data before opening the app and connecting. Alternatively I could keep a dedicated tablet in my car.TL;DR: great device for the price, be aware of the differences between WiFi and Bluetooth.
