Disocover services after disconnect BLE
Hello,
I would like to be able to disconnect from a BLE peripheral and reconnect to it without having to fully close the application. I have used the BluetoothLEDevice.Disconnect function. The BLE peripheral device returns to advertising. I am able to discover the device but unable to discover the services. This is because Discoverservices returns false.
Looking at the Heartrate sensor example I havn't found a anything relating to disconnecting from a device and reconnecting.
How do I properly disconnect from a device?
Why does discoverservices return false?

How long should it take for a question to be posted?
A week ago I asked a question. After I submitted it, a banner came up saying under review by moderator. Since then, no action, no communication and no posting of my question regarding Delphi Pro 10.2.3 and a problem getting Win64 as a target configuration on a Windows 10 Professional, 64-bit computer/OS.

Developing iOS and OSX applications
When I was in the Apple store the other day the sales person said that one can create iOS and OSX applications on their iPad Pro tablet.
As I am looking to expand into iOS and OSX versions of my applications, can I use an iPad Pro to compile my apps from within the Delphi 10.2.3 IDE? If so, can you point me to the documentation that shows me exactly how to set this up.
Thanks for your time.

How do I convert all my programs to Win64?
Last week, I updated to Delphi Professional 10.2.3 Tokyo on a Win 10 Pro, 64-bit laptop. Some of my newer programs allow me to add target platform as Win64; however some of my older programs, originally developed on 32-bit windows machines, do not allow me to add Win64 as a target platform, even though all help articles I've read say I should be able to do this if I have a 64-bit machine. The Add Platform button is greyed out for these older programs, some of which were developed under Delphi versions produced by CodeGear, while others were developed under XE versions of Delphi.
What do I need to do/change?

Problem with schemaadapter and blob filed
We have problems with blob-fields. We test a client/Server Project with firedac. At the server we save a query result with a schemaadapter. At the client we load the result from >>server FDSchemaAdapter.SaveToStream(Result, TFDStorageFormat.sfJSON); >>client LStringStream := TStringStream.Create(FDStoredProcGet.Params[1].asBlob); FDSchemaAdapter.LoadFromStream(LStringStream, TFDStorageFormat.sfJSON); It works fine. But if the result is greater than 256kb, we get an error. Invalid json Format. How can we use a result greater than 256kb? Thanks for help.

TImage
I am developing an application which is supposed to display random Images from a directory. It compiles and runs fine except it does not show the Pictures. Here is a snippet:
j := Selection.Count;
i := random(j);
name := Selection[i];
Caption := name;
ImageChosen.Picture.LoadFromFile(name);
ImageChosen.Stretch := true;
Am I missing something?

choose File Open from the main file menu or press the file Open button on the toolbar and the IDE shuts down.
I have installed XE5 on my Win7 64 bit desktop machine.
Odd behaviour for an IDE, choose File Open from the main file menu or press the file Open button on the toolbar and the IDE shuts down.
Select "Exit" on the File menu to shut down the IDE and it produces the File Open Dialog.
an environmental effect that swaps the actions of the Exit and File Open items...
How do I fix it?

Problem to launch Delphi 10.2.3
Hi, I used Delphi Professional edition with mobile plugin since at least Delphi XE4. I used lately Tokyo 10.2.2 and I'm under subscription. I have uninstalled it to install 10.2.3 with the iso. The installation is Ok but when I run Delphi 10.2 the license information dialog box. I have to enter my license number (I have try the both my Delphi license and my mobile pack licence) and when I click on OK, a dialog box says that I am not licensed for C++ Builder and Delphi don't start. I'm agree I have only Delphi but Delphi don't start... Thank you for your help. Grégory Bersegeay.

Issue when trying to install Tokyo 10.2.3
Environment: Windows 10 Pro machine with the actual updates.
Downloaded Tokyo 10.2.3 ISO. When trying to install Delphi, at 78 % of installation the InstallAware wizard does no more respond. Actual step: "Actualizing the Database-Express-Settings".
Some tries to install/uninstall any versions of Tokyo ended with the same issue. Same result after having uninstalled some leftover of Berlin and Tokyo versions how suggested on <https://community.embarcadero.com/article/articles-support/171-rad-studio> manually.
Any suggestions?

Question on parsing a json string with TJSONIterator
In using TJSONIterator and using the Return method, if the JSON string has gone down more than one level, Return does not get you back where the Next method will find the Key after that. How do you get back up two levels?

Problem with Ttreeview on migration to Tokyo 10.2.3
Just updated to 10.2.3 and its seems to have broken a couple of my apps.
Problem is in Ttreeview which I build in the designer UI with headline nodes and populate the subnodes at runtime.
To speed things up in the subnode population, in the form create method, I search for the headline nodes and assign the tree nodes to global Ttreenode variables.
That avoids having to search for the main nodes every time I add a child node.
This has worked on every previous version now on some of my apps (not all) this now crashes with an "Unable to insert node" error on the first attempt to add a child node to a headline node using
TreeView1.items.addchild(MainNode,AName)
On debug, somewhere between the main form Oncreate and OnActivate events, the Trreview has reallocated all its nodes and the pointer addresses have changed.
As a work around, I have moved the node variable setters from the form onCreate event to the OnActivate event.
I guess this must be the result of messing with the VCL code somewhere between 10.1 and 10.2.3?
