Comments on nRF Toolbox for Bluetooth LE for Android

★★★★★ Robert Montgomery · Mar 30, 2025

I used this at work to program firmware on IC chips presently installed on circuit boards.

★★★★☆ MAKUZA Albert · Jan 18, 2018

The best BLE base app for Android ever.

★★★★★ Harald Kubota · Mar 18, 2017

Works extremely well with Puck.js and is great to confirm the Bluetooth LE profiles and advertised data you can program to be sent by the Puck.

★★★★☆ James Hart · Dec 18, 2020

I Only used the DFU function but have used it several times and have found it straight forward and reliable

★★★★☆ Tore Forsgren · Aug 1, 2017

Great app for nRF developers. The UART app is a bit slow on the key respons. Would also be great to have sliders with configurable min, max values to generate UART data composed of a string with slider position inserted. A great way to put some stress on the Bluetooth link.

★☆☆☆☆ junaid ahmad · May 14, 2021

Can't adjust data type in UART. In IOS version of app I can select text or byte are but not in android version. Please update app.

★☆☆☆☆ Arjun Sonti · Sep 5, 2019

Scan stopped working after Android 10 update. It always says no devices found, but other apps are able to scan fine

★★☆☆☆ Krishian Kumar · Jan 8, 2020

When scanning for a Bluetooth device, doesn't find one when using mobile phone, (updating Selectric arc air firmware), this is a simple fix if your tech mided, instead of downloading the nrf toolbox download the nrf for mobile as when scanning for the Selectric arc air set it will definitely find which will enable you to update your Selectric arc air set,
