Wiki Page: Using and Deploying Psion Libraries/DLLs

Steven Cox — Wed, 24 Apr 2013 18:25:00 GMT

Beginning with Mobile Devices SDK version 3.3, there are several changes in which libraries to link to/reference and what to deploy to a particular device:

C++ applications no longer require a PtxSdkCommon.dll to be deployed to the target device (this functionality is built into the PtxSdkCppxxx.dll now)
C++ applications developed in Visual Studio 2008 require a different library (PtxSdkCpp2008) for each operating system supported. Visual Studio 2005 C++ applications use the legacy PtxSdkCpp naming convention
The folder structure has changed to denote which libraries are used where (e.g. ‘Studio2005’ for Visual Studio 2005 files, and ‘Studio2008’ for Visual Studio 2008 files)
.NET and Java applications still require PtxSdkCommon.dll to be deployed to the device
Most new features will be split into different DLLs (WLANEx), and they will be referred to collectively as Product Development Kits (PDKs)
The original features (found in the original DLLs) will be referred to as the Core SDK
There is a new .NET SDK for Compact Framework 3.5 (see <DRIVE>\Program Files\Psion Teklogix\Mobile Devices SDK V5.1\DotNet3.5). While this is the recommended assembly to target for your Visual Studio 2008 application, the DotNet2 assembly may also be used.

Below is an example breakdown of which .lib/.dll to use for a particular project using Psion Teklogix Mobile Devices SDK:

NOTE: Although there is a JAVA column for each Visual Studio example, that does NOT indicate that Java applications are built with Visual Studio.

NEW CHANGE: For MDSDK 6.0 and greater, "PtxSdkCommon.dll" has been renamed to "mdsdkcore.dll".

Overview

Remote Socket Calls do not Always Generate Errors in the Same Way as Windows Socket 2 Calls

Overview

The Psion remote sockets implementation behaves like a Windows Sockets 2 implementation; however, Psion remote sockets is a two-stage process with the communications server acting as an intermediary between the host and the mobile device.

This article describes issues that may cause problems when using a remote socket connection.

Communications Server Configuration

For information on configuring the communications server see the 9500 Series Communications Server Software User Manual on IngenuityWorking.

Psion Mobile Devices can be Offline, out of Range, or Inactive for Significant Lengths of Time

The remote host should not close the sockets connection during these times. If it does, the Psion mobile device must close any open sockets and reopen them. Recovery from this state is up to the application on the Psion mobile device.

Top

Synchronization Between the Communications Server and the Psion Mobile Device

When a Psion mobile device is out of range of a base station, socket calls are queued, or blocked, until the mobile device is back in range. If the socket state changes during this time, it is the responsibility of the application on the mobile device to recover from this state.

When a mobile device is powered up after it is powered down, or reset, it may not receive the terminal number previously assigned to it.

Each socket is a session on the Psion mobile device, and it is represented by a terminal on the communications server. One consequence is that a socket may remain open on the communications server for significant periods of time without a corresponding Psion mobile device session (a stale connection).

Top

Terminal Number Assignment

Terminal numbers are assigned dynamically by the communications server when a socket is opened: One session with one assigned terminal number for each socket. As a result, it may be difficult to determine from a Psion mobile device the terminal numbers assigned to it. Also, there is no guarantee a Psion mobile device that closes and then re-opens a socket will be reassigned the same terminal number by the communications server.

Top

Remote Socket Calls do not Always Generate Errors in the Same Way as Windows Socket 2 Calls

Due to the nature of the underlying protocol, socket calls (send, for example) do not immediately return errors to the application. If a socket call generates an error, it is usually the next call, or some following call, that actually reports the error to the application. This behaviour should not have any consequences, unless the application makes other assumptions; for example, that the successful completion of a send call guarantees delivery of a packet to the partner device (host).

Top

Available Bandwidth

As with any wireless device, the amount of bandwidth available to a mobile device is generally lower than that available to a wired device due to the overhead of the radio protocols, possible interference, etc. Applications should restrict the amount of data sent to the Psion mobile device (especially over narrow band and similar restricted-bandwidth media) to prevent poor response times.

Top

Binding to an IP Address/Port

The bind function on the Psion mobile device behaves in a slightly unusual fashion due to the nature of remote sockets. The bind call causes the communications server, rather than the Psion mobile device, to bind a particular IP address and port. As a result, every Psion mobile device making a bind call must specify either: a unique port number, or a unique IP address for the bind. Failure to do so results in one Psion mobile device either failing to successfully bind a port, or failing to successfully correct / accept connections. Psion mobile device IP addresses cannot be assigned using BootP or DHCP as the Psion mobile devices with narrow band radios may not have MAC addresses.

Top

Number of Remote Sockets Available is Limited

The following restrictions apply to the number of remote sockets in use:

•

A maximum of seven remote sockets can be open for the same Psion mobile device.

•

The maximum number of remote sockets that can be open on the communications server is defined in the communications server configuration.

Top

Address Matching on the Communications Server

When a Psion mobile device sends a socket bind request with a non-zero IP address as a parameter, the communications server attempts to create and use that IP address as an alias IP address. This is an alternate IP address that the communications server will send/receive packets from, in addition to its own native IP address. To create the alias the communications server chooses an interface with maximum number of matches between the alias IP address and the interface IP addresses. It makes binary comparison of the addresses. Any match with fewer than 16 identical bits is ignored, as it would be hard for a host to route to such an alias.

Here is an example of address matching:

10.128.0.154 = 0x0a80009a = 00001010 10000000 00000000 10011010

10.128.78.19 = 0x0a804e13 = 00001010 10000000 01001110 00010011
