## What is Bluetooth Terminal?

## Version 3 is now available ##

With Bluetooth LE Terminal you can easily prototype your Bluetooth Smart enabled hardware. Send individual bytes encoded as ASCII, HEX or Decimal numbers and receive data from your hardware accessory.

Test your data transfers even before having your own app!

# More Features:
• Send bytes as ASCII, HEX or Decimal
• See device's services and characteristics and their associated values
• Get information about your device such as name, UUID, and RSSI readings
• Setup a button matrix (game controller) to send different data with just a tap.
• Apple Watch support for button matrix
• Send the current time as a unix timestamp (seconds since 1970)
• Export current session as CSV
• Use the app in split-view or slide-over on iPad

If you have any questions about the app, or requests for features you would like to see, just write a short review or use the button inside the app to contact me!

* Some features may require an optional one-time in app purchase.

### 5/5 — Bester BT Scanner

*2026-02-16, version 3.4.1*

Mit diesem Scanner konnte ich mein python script anpassen so das der china Messchieber endlich daten sender Danke Top App

### 5/5 — Product:rice                                      My chop

*2025-11-20, version 3.4.1*

Good

### 3/5 — Titel ist schon falsch

*2025-11-19, version 3.4.1*

Es wird kein echtes Bluetooth unterstützt sondern nur BLE.

### 4/5 — My opinion

*2025-08-16, version 3.4.1*

I actually liked the app because it was a struggle to find something like that to connect my BLE and control, once I opened the app i was exited that the text command working perfect the when I wanted buttons control I found that i need to pay and I think it’s only buttons no joysticks or something else like that

### 1/5 — does not name.. does not detect some devices

*2025-04-29, version 3.4.1*

it does not name some devices, does not recognize others.. tried on ipad 12.9

### 5/5 — Good

*2025-04-08, version 3.4.1*

Easy and works well

### 2/5 — Pico ile Çalışmıyor

*2025-03-14, version 3.4.1*

Pico ile çalışmıyor. Gönderdiğiniz her komut harf harf iletiliyor. Sorun kodunuzda değil bu uygulamada. Bluefruit Connect kullanın.

### 5/5 — Thanks 🙏

*2024-06-23, version 3.4.1*

J’ai pas été capable de synchroniser mon casque d’écoute xbox à mon téléphone pendant au moins un ans.

En téléchargeant votre application, j’ai réussi à régler mon problème gratuitement en moins de 3 minutes.

Aujourd’hui , je suis un de vos fans!

### 2/5 — Controller buttons can’t send integers

*2024-04-05, version 3.4.1*

The controller buttons in the paid version cannot send decimal integers or hex, only ascii. Also cannot send integer zero (0x00, ascii null character) at any time.
