B4i Library iSD BLE Printer

I am happy to present my library to print with Iphone (and iPad) with Bluetooh (BLE). Now I can print the images. If you want to have the activation code (Freeing all the functions) contact me in private.
(For B4J versione see Here, for B4A versione see Here, for ZEBRA printer Here)

This version requires an activation code. If you don't have a code, it will work in DEMO mode and you can print for just one minute every 4 minutes.

Yes, I copied the files on the Mac server ... I have no problem compiling ... the program gives an error when running ... the program is installed on the simulator but gives an error and the program closes ... If the files are not copied at all, the program Cannot be installed ...
Did the library files change in the new changes?

No I'm sorry there is no change.
But the thing I want to point out to you is that line 12 is not an instruction. It is considered by the compiler only if you are compiling as a library, but in release or debug it is ignored. An error in that row is strange.

Try the updated example and open it if it signals you an error and in what line

Problem with simulator

Hi everyone, as you may have guessed, I'm new in the B4I field. With B4I rev 5.50, I tried to run the "Hello World" program. the application is compiled correctly. Selecting "Tools-Simulator" and then F5 (Run): the simulator starts working and then stops immediately. The following list of...

Compile Fails

Hi there, My first foray into using B4i! I am running B4i on Windows machine under Parallels on a Mac. I have started the B4i Server, but when I try to compile I get this message... B4i Version: 5.51 Parsing code. (0.00s) Building folders structure. (0.03s) Compiling code. (0.01s)...

Could you have version 5.5 on the server? It doesn't seem like a library problem

Thank you .. it was correct ...
But now I can not print photos and barcodes ...
And there is a problem with how to connect to the printer, and any device with Bluetooth on is connected, and every time we have to click on the scanner button of the printer ... Is it possible that it displays the list of devices and we click on the printer in question?

As explained in POST 6, this function is not yet active.
For the connection, I will test and answer you as soon as possible
 
I need to print photos and text in my new project ... Now it prints the text with your library, but the photo has a problem ... I use b4i 6.5 ...

Hi,
I have use the src of BlePeripheral2.java to try to make a new library BlePeripheral4.java to connect peripheral at a central Nordic UART
i have change :

BluetoothGattService service = new BluetoothGattService(longUUID("0001"), BluetoothGattService.SERVICE_TYPE_PRIMARY);
charRead = new BluetoothGattCharacteristic(longUUID("0003"), BluetoothGattCharacteristic.PROPERTY_READ | BluetoothGattCharacteristic.PROPERTY_NOTIFY, BluetoothGattCharacteristic.PERMISSION_READ);
charWrite = new BluetoothGattCharacteristic(longUUID("0002"), BluetoothGattCharacteristic.PROPERTY_WRITE, BluetoothGattCharacteristic.PERMISSION_WRITE);
charRead.addDescriptor(new BluetoothGattDescriptor(longUUID("2803"), BluetoothGattDescriptor.PERMISSION_READ | BluetoothGattDescriptor.PERMISSION_WRITE));

and in

java.util.UUID longUUID(String shortName)
return UUID.fromString("6e40" + shortName + "-b5a3-f393-e0a9-e50e24dcca9e");


I call the new library the start find ok but the central don t see the this peripheral
can you help me

best regards
Thanks
 
Hi, to ask questions about how to make libraries you have to go to the appropriate part of the forum to ask questions.
This is dedicated to presenting and distributing library.

Also I believe you are wrong platform. Here it is for Apple devices running iOS. I don't see what Java is about.

If you are trying to write something for Android write your question in the appropriate part of the forum
 
Hi @narek adonts ,
Unfortunately I have not made progress, it seems that the data sent is too much or too fast and is not being processed.
In debug mode it works, but extremely slowly, a printout is obtained after 10 minutes or more.

I have seen Software for iOs that work well and fast, so I am doing something wrong in the transmission of the images
 
Update 0.04
  • Add ESC POS command
  • fix bug
 
After 3 years of trying I realized that I was unable to print due to the old iPhone device. Today I tried with a recent iPad and the printing works fine.

Soon I will release the version that prints. Obviously the free version will not contain image printing.
 
Update 0.24
  • Addition of the PrintBitmap function (Requires iPhone 8+ for correct printing speed)
