Are there any methods that a Sim Toolkit applet is selected when phone boots or SIM card is inserted on phone?
I want an applet on a SIM card that automatically executes some commands and display a message when SIM is installed on phone or phone boots.
STK Applet got 3 methods 'process','processToolkit'and 'install'.
I don't know if each of methods 'process','processToolkit' can be called during phone boot or SIM installation on phone?
This is possible. You have to register the event EVENT_PROFILE_DOWNLOAD during the applet installation.
toolkitRegistry = ToolkitRegistrySystem.getEntry();
toolkitRegistry.setEvent(EVENT_PROFILE_DOWNLOAD);
// in case you need a menu later, too:
toolkitRegistry.initMenuEntry( ...
When the SIM is started the modem will always execute the TERMINAL PROFILE commmand. This will trigger the registered EVENT_PROFILE_DOWNLOAD by processToolkit. In case you have a menu the menu selection will be handled also by processToolkit. The event will be EVENT_MENU_SELECTION then.
From processToolkit you can execute any necessary behavior, e.g. displaying a text.
ProactiveHandlerSystem.getTheHandler().clear();
ProactiveHandlerSystem.getTheHandler().initDisplayText((byte) 0x81, 0x04, array, offset, (short) (length));
byte res = ProactiveHandlerSystem.getTheHandler().send();
return res == RES_CMD_PERF;
The array would be the ASCII encoding of your text.
Consult the UICC API as startign point.

Background:
I was given a task for college to implement an elevator's source code for an Arduino UNO with a user interface shield that contains: a 7-Segment display and a total of 8 buttons, one for each floor plus two to control the doors. The floor buttons also have an LED.
The hardware is only for human user input, but the brains is made entirely within Erlang. Before we got to implement this project in hardware, we used a simulation that uses wxWidgets to display the following UI: a window that displays the elevator doors, 6 more windows for each floor, and a window for the internal button array of the elevator. This button array is what I'm trying to implement within an Arduino.
Some code:
Our teacher gave us some confusing notes about the use of erlang:open_port/2 that I can't understand yet. The testing code we're using is the following:
-module(proUSB).
-export([start/1, order/2, loop/1, exit/2]).
start(Port_alias) ->
Port = open_port(Port_alias, []),
Pid = spawn(proUSB, loop, [Port]),
port_connect(Port, Pid),
{Port,Pid}.
order(Port,Value) ->
port_command(Port,Value).
loop(P) ->
receive
{P,{data,A}} ->
io:format("Received: ~p~n", [A]),
loop(P);
{'EXIT',P,_Reason} ->
port_close(P),
io:format("Unexpected finalization~n",[]);
exit ->
io:format("Proces finalization~n",[]);
Other -> io:format("Fi ~p~n",[Other])
end.
exit(Pid, Port) ->
port_close(Port),
Pid!exit.
As I've understood and successfully tested in Windows Subsystem for Linux (WSL) with the code mentioned above, all I have to execute in the Erlang shell is
> {Port, Pid} = proUSB:start("/dev/ttyS6").
{#Port<0.7>,<0.82.0>}
This will open the port. I can now send orders to the Arduino USART in the protocol we've designed. To light up the number three in the 7-segment display, we write
> proUSB:order(Port,"D3").
true
Now, if we press the floor button 1, you can see in the terminal
Received: "B1\n"
Received: "\n"
Received: "B1\n"
Received: "\n"
My question:
If I want to use Windows Powershell to do the same connection to the serial port, my teacher told us to write "COM6" instead of "/dev/ttyS6", but as I have tested, I can't get a connection but I get this error
> {Port, Pid} = proUSB:start("COM6").
** exception exit: einval
>
What am I missing? If WSL works with "/dev/ttyS6", why shouldn't it work with Windows when I can use the serial port with "RealTerm: Serial Capture Program"?
I use a RN4020 BLE Module to communicate with the VALRT BT Button: https://vsnmobil.com/products/v-alrt/specs
Problem is, I need to send "80BEF5ACFF" within 30sec after connect to the specific private UDID "FFFFFFF5-00F7-4000-B000-000000000000" (see reference: https://github.com/HoyosIntegrity/V.ALRT-bluetooth-spec)
Problem is, I always get "ERR" back from RN4020.
Here is my Initialisation Code (which works):
sf,2 //Factory Reset
+ //echo on
sr,92000000 //configure as Master
r,1 //reboot
F //search devices
X //stop searching
E,0,001EC026C931 //connect to device with mac: 001EC026C931 which is my device
B //Bond
Get a "Connected" back and the Button quit it with a Beep.
Now I tried to Write
CUWV,FFFFFFF5-00F7-4000-B000-000000000000,80BEF5ACFF
with and without "-" but allways get a error back. At github are samples for Android and iOS but its not clear for me what I have to send...
Think I forgotten a prestep, but I dont know which one.
Strange is, when I connect and send "LC" I get this back:
180A

That are some of the services but not all.
This is UWP code for getting BLE devices. Why I get bleDevice == null for some devices? I didn't find any documentation which explains that.
var devices = await DeviceInformation.FindAllAsync(BluetoothLEDevice.GetDeviceSelector());
foreach (DeviceInformation di in devices)
{
Debug.WriteLine(di.Name);
BluetoothLEDevice bleDevice = await BluetoothLEDevice.FromIdAsync(di.Id);
if (bleDevice == null) {
Debug.WriteLine("--- NULL ----");
continue;
}
Debug.WriteLine(bleDevice.Name);
}
I noticed that I get bleDevice != null for BLE devices that HAVE exclamation mark with STATUS_DEVICE_POWER_FAILURE in device manager in Windows.
I get bleDevice == null for BLE devices that DO NOT HAVE exclamation mark in device manager.
I got the same problem. the previous answer from Chi Lee is in fact good but not enough detailed on how to do it (for non-experts;-) ).
Here the detailed process (assuming you have a c# project under Microsoft visual studio):
Double click the properties field under your project: this will open a new tab
in the opened tab, select Application in the left then click Package Manifest... button
A new tab named "package.appxmanifest" is opened. Select, inside it, the Capabilities tab
Check Bluetooth field under capabilities
Save and recompile your project.
The BluetoothLEDevice.FromIdAsync(di.Id) will no more return null, provided that you already have paired devices (either in your program or manually in Windows .
You have to add Bluetooth capability in your appxmanifest file.
I'm trying to send key stroke to an external application in java using jna.
It sends VK_DOWN key, also that application has a shortcut for ctrl+down which makes something very different. My application sends around ~15 down key with 1 sec in between, and if user happens to click CTRL during it while working on a different window, it breaks the application(treats it as ctrl+down).
I checked the keyboard messages via Spy++, compared mine with AutoIt, they are exactly same messages.
ControlSend("window_title", "", "", "{DOWN}")
This AutoIt code works perfect, even if I click ctrl when window is active or inactive, it does not interfere with down key.
My code on the other hand:
User32.INSTANCE.PostMessage(handle, WM_KEYDOWN, wparam, lparamDown);
User32.INSTANCE.PostMessage(handle, WM_KEYUP, wparam, lparamUp);
has exactly same messages, but it doesn't work.
I tried sending control up before sending down key but to no avail.
Spy++ output:
<14335> 00011456 P WM_KEYDOWN nVirtKey:VK_DOWN cRepeat:1 ScanCode:50 fExtended:1 fAltDown:0 fRepeat:0 fUp:0
<14336> 00011456 P WM_KEYUP nVirtKey:VK_DOWN cRepeat:1 ScanCode:50 fExtended:1 fAltDown:0 fRepeat:1 fUp:1
My ctrl clicks are not even on target application so why does it treat it as such? Should I use a hook?
i use customer message and send it broadcast over radio channel, i use example 6 (CounterSend ) from this link .
when i build this project as micAz on mote 1, after this i use Xsniffer (TOSBase) on the mote that i will use it on the serial usb board (520).
after that i open Xsniffer program to see the radio packet and they appeared as following :
on other hand, to use Xserver i use XMeshBase then type on cygwin terminal :
xserve -device=com4
i got this!! but i can't understand what it received ?
how can i parse the data received ?? and named them as i want ?? ex: i need first byte be the source ??
how to do that ?
