However, if you’re interested in accessing pre-released versions of a spec (such as 0.9 revisions) or getting a head start on cutting edge adopted specs, then you can access them after signing up to be a member (also free), at the Adopter level. When you run into issues or have questions about certain technical aspects of Bluetooth Low Energy, the official Bluetooth specification documents are the best references to go back to.Īccess to the released Bluetooth specification docs is completely free. While the Bluetooth ® specification documents are not considered tools per se, they are still the main reference documents for every Bluetooth developer – mobile or embedded.

Oscilloscope: Used to get more accurate measurements and finer tuning of your power consumption.

Digital Multimeter (DMM): Useful for measuring average current draw and peak current (e.g.

There are different tools that can be used to measure the power consumption during development and testing to help you optimize for low power. However, low power consumption doesn’t come by default, and both the firmware and hardware designs play an important role in how good your device is at minimizing power consumption. Bluetooth Low Energy is usually selected as a wireless technology in a product for two main reasons: the proliferation of Bluetooth low energy in smartphones and the low energy consumption that comes with it (allowing you to design devices that can last for years on tiny batteries). The Low Energy part in Bluetooth ® Low Energy is there for a reason.

Low-cost: TI CC2540 USB dongle sniffer, Nordic nRF sniffer, Ubertooth One.

High-end/commercial: Ellisys sniffers, Teledyne LeCroy sniffers (formerly Frontline), the Spanalytics PANalyzr.

Using a Bluetooth ® Low Energy sniffer can help tremendously in debugging problems with the connection and data transfer between the peripheral and central device.

The low-cost sniffers usually suffer from a few limitations, such as the lack of advanced features on the companion desktop software side as well as not being able to scan the three primary advertising channels simultaneously. More advanced, higher-cost sniffers (anywhere in the range of $1,000-$30,000+).Simple and low-cost sniffers (think in the range of $50-$100) that are usually based on development kits.While a Client emulator is usually used to act as a central device to read, write, and subscribe to notifications/indications of characteristic values of the peripheral device, the sniffer acts in the background (usually without requiring you to modify any of your system’s behavior).īluetooth ® sniffers come in two main varieties: The difference between a Bluetooth sniffer and the Client emulator apps mentioned previously is that sniffers can spy on the communication between your central and peripheral devices. Nordic nRF Connect app ( iOS, Android, Desktop)Ī Bluetooth ® sniffer (or protocol analyzer) is one of the most useful tools that a Bluetooth developer can’t do without.These types of apps allow you to scan for nearby advertising Bluetooth Low Energy devices, connect to one of these devices, discover their services and characteristics, and read from/write to the characteristic values as well. It’s also very helpful for testing out new changes and during development. This tool can be very helpful, especially when you don’t have a companion mobile app ready to interact with and test your Bluetooth device. This can be either a mobile app (iOS or Android), or a desktop application connected through a Bluetooth ® Low Energy dongle (or internal Bluetooth Low Energy chipset). In this article, I will provide a list of the four most essential tools for developing a Bluetooth Low Energy product and app. Whether you’re a mobile developer or a firmware developer working on a Bluetooth ® Low Energy product, there is a set of essential tools that you should utilize for developing your application in the most efficient way. One of the biggest challenges of learning any new technology is knowing which tools you need in order to get started on the right path.
