#Arduino bluetooth dongle tutorial full

With a collaborator, we could knock out a full project in a week or two and release it open source for others to use. (Would anyone conversant in javascript and html like to join me in this endeavor? I can readily code or fix the BLE interface as needed, but formatting the HTML results in javascript is difficult at my level of experience. I have a design in mind for managing the r/w attributes and tabulating/showing old values so you can write characteristics and see what changed, but it’s starting to hard press my HTML/javascript ability to show it. Link below for anyone who wants to use it. Unfortunately, my javascript/web-fu is weak, and I stopped after the reading/showing characteristics step. Useful as a first step in BLE reverse engineering, to find the device address and list of services/characteristics to explore.

If the characteristic is known or in a known format (vendor ID, serial number, &c), it will format and show the values as well. The interface is ‘sorta like the file manager, in that it lists all the BLE devices, and you can open them like directories to see the services, open the services to see characteristics, and so on. I built a web page server for RasPi that allows the user to interactively explore the BLE landscape using a browser. Posted in Software Hacks, Wireless Hacks Tagged ble, bluetooth low energy, intercept, sniffing, wireshark Post navigation While naturally the finer points will differ, this same overall workflow should allow you to get control of whatever BLE gizmo you’ve got your eye on. Once the ESP32 can send commands to the lamp, it only takes a bit more code to spin up a web interface or REST API so you can control the device from your computer or other gadget on the network. In the end, takes an LED lamp that could only be controlled with a smartphone application and turns it into something he can talk to on his own terms. Obviously this technique might not work on more advanced devices, but it should still give you a solid base to work from. In this particular application, it’s enough to simply replay the commands using the ESP32’s BLE hardware, which is explained in the third video. It’s worth noting that little attempt is made to actually decode what the commands mean. That’s where things really start heating up, as demonstrates how you can intercept commands being sent to the target device. The first video in the series is focused on getting a Windows box setup for BLE sniffing, so readers who aren’t currently living under Microsoft’s boot heel may want to skip ahead to the second installment.

He covers how to get a cheap nRF52480 BLE dongle configured for sniffing, pulling the packets out of the air with Wireshark, and perhaps most crucially, how to duplicate the commands coming from a device’s companion application on the ESP32. Well, watching this three part video series from would be a good start.

By extension, from fitness bands to light bulbs, it’s equally likely that you’re going to want to talk to some of these BLE gadgets at some point. If you fire up a scanner on your phone and walk around the neighborhood, we’d be willing to bet you’d pick up dozens if not hundreds of devices.

Bluetooth Low Energy (BLE) is everywhere these days.
