Near Field Communication
There's a new Mac app called Serial available on the App Store. Full disclosure- I wrote it. We got tired of having to find and install drivers for different serial adapters and devices we have here in order to administer Cisco switches, so we wrote our own terminal that uses its own built-in drivers for the most common chipsets available. Get Console is a powerful and complete terminal app that provides physical serial console access to network and other equipment as well as SSHv2, Telnet, Scripting, TFTP Server, full Logging, integration with Dropbox, iCloud and instant Screen Sharing. Please read below for Full information.
It includes a basic Terminal Emulator, a Protocol Analyzer and a serial port monitor to watch for connections and removals of serial ports. Allows control of RTS and DTR. A Raw mode that displays ASCII control characters (less than 0x20 or greater or equal to 0x7f) will be printed as two hex digits in between angle brackets. When using the serial communication we transmit the multi-bit word bit after bit (when at any given moment only one bit will pass). Transmitting the word 10011101 using serial communication. Using the parallel communication: When using the parallel communication, however, the number of bits will be transmitted at once from one computer to the. One thing that sets this messaging app apart from most others is that you don't have to make a user account to get started. Just enter your name and start adding contacts by their phone number or email address. The app is free, but there are in-app premium options for advanced features like ringtones, a voice changer, message expiration, and more.
Near Field Communication (NFC) enables devices within a few centimeters of each other to exchange information wirelessly. iOS apps running on supported devices can use NFC scanning to read data from electronic tags attached to real-world objects. For example, a user can scan a toy to connect it with a video game, a shopper can scan an in-store sign to access coupons, or a retail employee can scan products to track inventory.
For developer guidance, see Core NFC.
In-App Tag Reading
An app can enable single- or multiple-object scanning when the app is active, and display a scanning sheet whenever the user is expected to scan something.
Don't encourage people to make contact with physical objects. To scan a tag, an iOS device must simply be within close proximity of the tag. It doesn't need to actually touch the tag. Use terms like scan and hold near instead of tap and touch when asking people to scan objects.

Use approachable terminology. Near Field Communication may be unfamiliar to some people. To make it approachable, avoid referring to technical, developer-oriented terms like NFC, Core NFC, Near Field Communication, and tag. Instead, use friendly, conversational terms that most people will understand.
Use | Don't use |
---|---|
Scan the [object name]. | Scan the NFC tag. |
Hold your iPhone near the [object name] to learn more about it. | To use NFC scanning, tap your phone to the [object]. |
Provide succinct instructional text for the scanning sheet. Provide a complete sentence, in sentence case, with ending punctuation. Identify the object to scan, and revise the text appropriately for subsequent scans. Keep the text short to avoid truncation.
First scan | Subsequent scans |
---|---|
Hold your iPhone near the [object name] to learn more about it. | Now hold your iPhone near another [object name]. |
Background Tag Reading
Background tag reading lets people scan tags quickly any time, without needing to first open your app and initiate scanning. On devices that support background tag reading, the system automatically looks for nearby compatible tags whenever the screen is illuminated. After detecting and matching a tag with an app, the system shows a notification that the user can tap to send the tag data to the app for processing. Note that background reading is disabled when an NFC scanning sheet is visible, Wallet or Apple Pay are in use, cameras are in use, the device is in airplane mode, and the device is locked after a restart.
Support both background and in-app tag reading. Your app must still provide an in-app way to scan tags, for people with devices that don't support background tag reading.
Very interesting post! I have some problems:
![Mac Serial Communication App Mac Serial Communication App](/uploads/1/3/4/2/134256653/203092848.jpg)
1) When i open the 'Serial monitoring' in Arduino IDE, the Cocoa application blocks as the port resource is busy
2) When i click on one of the two buttons, tx/rx lights flicker on the Uno card and the LED_BUILTIN goes on for less than a second, then goes off but never stabilises
3) In the Arduino IDE serial monitor, when i send 'i' or 'o', the LED_BUILTIN led switches on and off correctly
Serial Communication Software
I'm running MAC OSX Sierra and get a warning saying that my target OS is lower than the deployment target (which i had to change in the project properties)

Thank you for your help
