iOS Unified Client 3.0.0 -> 3.0.1

pmshm

After updating from version 3.0.0 to 3.0.1 I get a connection error:

Error: 65, Unsupported protocol version: TLCP-2.1.0

Someone got the same problem or a solution?

Hello,

which Server version are you connecting to?

Alessandro.Carioni

The error is strange since client 3.0.1 uses TLCP-2.0 as internal protocol and should be compatible with 3.0.0 version.

Maybe have you installed inadvertently the version 4.0.0 of the client, released the 20th December 2017, which actually uses TLCP-2.1 and needs Server 7.0?

We confirm this to be an unfortunate compatibility bug between version 3.0.1 and Server 6.1. We are now delivering an "hotfix" on the 3.0.1 version.

If you installed the iOS Client Library via CocoaPods, clean its cache to force it to download the hotfixed version. Run the following command:

pod cache clean Lightstreamer_iOS_Client

If it asks which version, choose the 3.0.1 version. If 3.0.1 version is listed more than one time, repeat the command.

Once the cache is clean, remove the "Pods" directory and run CocoaPods again on your project:

rm -Rf Pods; pod install

If you installed the iOS Client Library manually, just re-download the binary from the original link:

www.lightstreamer.com/repo/cocoapods/ls-ios-client/3.0.1/ls-ios-client-3.0.1.zip

Then replace the framework in your project.

Let us know when the problem is fixed.

Bingo, the hotfix solved the problem.
Thanks.
