A brand new Android app from TSL^® has just been published on the Google Play store! RFID Sensor Tag Explorer demonstrates the use of passive sensor tags with TSL’s Handheld UHF RFID Readers. Passive Sensor Tags are wireless and battery-free sensors that can measure parameters like temperature, strain, pressure, humidity, and motion.

• A free demonstration app, compatible with ‘Asygn’ Passive Sensor RFID Tags
• Measure and monitor critical parameters like temperature, strain, pressure, humidity, and motion
• Passive Sensor RFID Tags can be placed in almost any environment and help to reduce maintenance. They are suitable for use in hazardous environments or within fast rotating parts.

This new release of the native Android SDK introduces ASCII Protocol 3.0 – the backwardly compatible, evolution of TSL’s ASCII Protocol 2. The ASCII Protocol 3.0 update provides support for TSL Series 3 Readers, such as the recently introduced 3166 UHF RFID RAIN Reader.

Additions to the protocol include:

• The LinkProfileCommand to allow access to the new, faster Series 3 RF Modes.
• A SelectPause parameter, on the ReadTransponderCommand, to provide the carrier wave needed for optimal reading of Magnus S3 temperature Sensor Tags e.g. HID Sense Passive, Axzon etc…
• A new SystemCommand that can be used to alter the baud rate of the ePop-Loq connection and adjust the volume of system sounds, such as the power on beep.
• An AlertVolume parameter, on the AlertCommand, that allows fine-grained control of the alert volume (0-100%).

See the included “Version History.txt” file for full details.

The SDK also sees the introduction of:

• An improved Inventory Sample Project that can access the Series 3 Reader RF Modes for significantly faster tag read rates.
• A new Sample Code project, for accessing Magnus S3 Temperature Sensor Tags demonstrating all the steps required to reliably access temperature, sensor and RSSI values.
• A reworked LicenceKey Project that demonstrates the use of an Asymmetric Public Key Cryptography signature approach.

The v2.8.0 SDK is built for Android API Level 34.

Apple introduced a breaking change in their APIs that was only present in the US version of the OS. This prevented US devices running iOS 17 or higher from exporting inventories in RFID Explorer.

TSL has identified and resolved the issue so the latest version of RFID Explorer for iOS can now export inventories again.

RFID Explorer for Android has now been updated to v2.15.00

Support has been added for the newly released 3166 Rugged RAIN RFID UHF Reader including control of the various Reader RF Modes, faster ePop-Loq speed and support for Magnus S3-based temperature sensor tags.

For all TSL Readers:

• The Read/Write screen has seen an update to allow tags to be selected based on the TID or User memory banks, in addition to the EPC memory bank.
• The Inventory screen has had a refresh with improved responsiveness.

The latest version of the app can be downloaded from the Google play store, or the .apk file can be downloaded here.

TSL^® have updated their Xamarin .NET Standard Development SDK to version 2.1.0 to provide compatibility with the Google 2022 API requirements for Android (API Level 31).

The sample project in the SDK release has been updated to use the Tsl.AsciiProtocol v1.6.0 NuGet package – which is required when targeting API level 31+.

When Android 12+ or later is targeted, the following permissions must be both declared in the AndroidManifest.xml and obtained at runtime:

• Manifest.Permission.BluetoothConnect
• Manifest.Permission.BluetoothScan

Until these runtime permissions are obtained from the user, no Bluetooth^® devices will be available.

We provide an example of how to obtain these permissions in the Sample.Connections.Forms.Android sample project.

TSL^® have updated their native Android SDK to version 2.5.0 to meet the Google Play Android 12 (API level 31) requirement that comes into effect on November 1, 2022.

If your app is targeting API level 31+ then

1. you will need to update your app to use the Rfid.AsciiProtocol library  (v3.0.0), included in the latest SDK.
2. You will also need to update your app to issue a request for Bluetooth® permissions, where appropriate.

The latest SDK contains updated Sample Projects to demonstrate one way to do this – all built against the latest API Level 33.

In addition, three Sample Projects (Inventory, ReadWrite and ConfigureBarcode) have been re-written to demonstrate the use of the SDK in the latest Android Studio, Basic Activity app template.

This release also addresses a null pointer error that occurred when running previous Rfid.AsciiProtocol libraries (v2.5.0 or lower) on Android 12+ devices.

TSL^® have updated their native Android SDK to version 2.4.0. This release provides:

• An update to the HF LF Support Sample code.
• A demonstration of the new ReadTagCommand for use with the 2173 HF/LF Reader.
• Improvements to the SignalStrengthResponder to indicate when multiple matching tags are present.
• An updated Developer Guide.
• Comprehensively updated Javadocs to fill in missing property descriptions.

A brand new Android^™ app has just been published by TSL^® on the Google Play store. 2173 Explorer is a dedicated app built to demonstrate the performance, functionality and versatility of the 2173 Bluetooth^® LF/HF RFID Reader.

The app demonstrates how, using the 2173 Reader, a simple inventory of Items, tagged with a wide variety of HF and LF tags or 1D and 2D barcodes, can be achieved. This inventory is then available to other apps, on your device, using the familiar Android sharing dialog.

Features include:
▪ Generate a list of unique HF/LF transponders and barcode item identifiers
▪ Read the memory of tags – Mifare Classic, ISO15693 and SRX tag types are currently supported.
▪ Share the list of scanned items or save it to the Android device.
▪ Control detection of the HF and LF tag types supported by the 2173 Reader.
▪ Configure the operation of the 2173 trigger to match your scanning requirements.

TSL^® have updated their native Android SDK to version 2.3.0. This release brings an update to the Inventory sample project to demonstrate two of the most requested features: continuous inventory and the recording of only unique tags.

In addition, the Rfid.AsciiProtocol-Library and all of the sample projects have been rebuilt using Android API Level 30 to meet the latest Google Play Store requirements.

New commands include:

• TSLFindTagCommand (for series 21xx Readers) – controls the Reader’s tag finder operation
• TSLBlockPermalockTransponderCommand – to allow tags to be block permalocked
• TSLAutorunCommand – allows the SD-Card’s ‘auto.txt’ file to be read, written or deleted.

The latest TSLAsciiCommands framework is now available in the new XCFramework format for Xcode 12 users. We have also audited the API to improve type-safety in Swift apps.

Finally, the included documentation has been completely overhauled and now provides a fresh, modern look, an updated ‘Getting Started’ section, improved enum type documentation and both ObjC and Swift interfaces for all commands.

This release can be downloaded as a zip file here (free registration is required to download files).
