Rfcomm and more!

This latest version of Best Calculator, IOT Edition includes a support for some pretty exciting new devices!  Firstly there’s the high-precision DPS310 from Infineon when attached to a IFX_NANOHUB Bluetooth board.  Then there’s the Ardudroid system that lets you control Arduino devices through the common Bluetooth COM add-ons.  And the last device specialization is the LittleBot from Slant Robotics!  What all these devices have in is that they are all programmed through a classic Bluetooth Rfcomm interface — otherwise known as an SPP (Serial Port Protocol) interface.  This is a conversational type interface, where you send and receive bytes to and from the device in an unstructured way.

And the regular Best Calculator users aren’t forgotten either.  Thanks to popular demand, Best Calculator now supports an Engineering mode display.  Engineering mode is like the exponential mode but the exponent is always divisible by three.  That keeps the units neat and tidy, and matches more closely how numbers are presented in Engineering books.

There are even more new features detailed in the Release Notes section of the manual.

Want to try it out?  Best Calculator and Best Calculator, IOT Edition are version 3.10 on the Windows store.


More TI goodness! Plus EddyStone and RuuviTag!

The newest version of BC Basic for Best Calculator, IOT Edition includes support for more Bluetooth devices!  The puck.js device from http://puck-js.com , the RuuviTag from http://ruuvi.com and (finally!) support for the TI SensorTag 2650.  The SensorTag early firmware, BTW, didn’t work with Windows; I have had success with firmware 1.4.  There’s also support for the nifty TI Watch (display) DevPack! The manual is no reaching 350 pages (!) with the latest additions, and there are 11 sets of samples for different devices. 

The most exciting Bluetooth addition is that supporting the RuuviTag also means adding support for EddyStone beacons and Bluetooth advertisements in general.  You can now watch for Bluetooth devices that are advertising, for EddyStone advertisements, for EddytStone-URL advertisements and finally for the RuuviTag EddyStone-URL in particular.

Best Calculator, IOT edition is on the Windows store for Windows 10 devices and phones.

More Bluetooth!

The first IOT edition of Best Calculator is now greatly expanded.  New devices that are directly supported with simple interfaces are the newest TI 1350 SensorTag, the MetaWear MetaMotion device from their successful Kickstarter and the super-popular BBC micro:bit.

But there’s much, much more!  All editions — including the class “free with no ads” version — get new Graphics support, more screen options, and bunch of bugs fixed.  The IOT edition can read and write files with CSV and JSON support, can connect to HTTP endpoints including the new Microsoft Flow.

And as always, the manual is available from CreateSpace.

It’s Programmable!

Exciting news for Best Calculator for the new school year: it’s programmable! The main keyboard has been squeezed in a bit to add an entire new row of keys.  The keys are marked P1, P2, P3, P4 and P5. Each key can be bound to a different program.  You can use any of the sample programs that come with Best Calculator, or you can write your own in BC BASIC!
