I've been through this site and many others multiple times but to no avail. So am forced to post a fresh new question here. Is it possible access a SIM loaded STK application from a j2me app running on the phone?
(JSR-177) Security and Trust Services API has an optional package called SATSA-APDU you can use this API to exchange messages with the SIM card. This chapter from the SATSA guide explains how to use it.

I am a developer and I have a Bluetooth Lamp that has RGB and Day/Warm Light that has a third party App to control it.
My goal is to do some automation with my Lamp.
Is there a way to read what this app is sending to my Lamp is order to simulate its functionality? The thing is this App is not possible to integrate with my Google assistant so I am trying to find a way to do it my self by making my own mobile application to control my Lamp.
Or maybe my question should be something like: is there a generic App that can control generic Bluetooth Lamps?
Any information is greatly appreciated.
You could either hack the hardware itself, or you could simply snoop on the communications to hack in to the lamp controls.
Otherwise, I would check out integration platforms like IFTTT, which allows some customization of control with proprietary systems.
Hi I'm not very good with coding but I'm trying to learn as much as I can. I've been looking for tutorials on how to create an internet call app on android studio. So far I haven't found any. If anyone knows a process that could guide me I would very much appreciate it.
You can use android's own implementation
Session Initiation Protocol
from docs
Android provides an API that supports the Session Initiation Protocol
(SIP). This lets you add SIP-based internet telephony features to your
applications. Android includes a full SIP protocol stack and
integrated call management services that let applications easily set
up outgoing and incoming voice calls, without having to manage
sessions, transport-level communication, or audio record or playback
directly.
or other third-party libraries like following.

I am working on IoT project over google cloud. I use Publish/Subscribe to allow devices contact each others. I developed the backend system using nodejs, then I will develop Mobile app that will use google library to publish/subscribe.
The problem that I face now is that. Does google have any C/C++ Library for contacting PubSub/googlecloud API or not, and if not, is there any alternative way to keep embedded devices (programmed in C/C++) updated with mobile applications actions.
Note: I need real-time control between mobile app and embedded device.
Thanks
Google Cloud Pub/Sub has a HTTP/JSON based API (under the API Reference tag in the sidebar), so you can roll your own library in this case.
The client APIs that Google currently supports are listed here. If you can run Go or Java on your embedded device (both a lot less common than C/C++ on embedded devices, and usually only supported if you stretch the definition of "embedded"), you can have a fully-supported client library.
I need to develop a project based on Bluetooth in mobile. Since I am new to j2me I studied some of the articles and run the project until the discovery of devices and services. I need to communicate between devices and transfer the desired files. I search code for client server communication through Bluetooth and got it but I didn't know how to run those code and implement further.
I have go through articles and I can run client server communication. Now I need to transfer the file and communicate to the user which was beyond the limit of my mobile through the another mobile which was within my limit.
JSR82.com has many articles and tutorials about how to use bluetooth from J2ME.
Better you refer the book, "BLUETOTH APPLICATION PROGRAMMING WITH JAVA API" by C.Balakumar. It is helpfull to you.
I am trying to use the new OTA enrollment and device management capabilities in iOS 4 to provide wireless app distribution for the enterprise. So far, I have come across a lot of third party MDM providers that seem to charge by the device. I don't believe this is something very hard to do on our own, especially as a prototype.
My search has led me to some open source software for SCEP. Together with the OTA configuration reference from Apple, I want to believe that the next step would be to actually implement an MDM server. Now, the WWDC talk had slides on various MDM queries supported by iOS 4, including installing and removing provisioning profiles, but there's no reference implementation or even exposed API that I could find.
Does anyone have any experience trying to fully develop an enterprise distribution and management system without third party software?
MDM providers that I've seen are acting as SCEP proxies so that you don't have to expose your certificate server to the internet.
The best open source SCEP server I've found so far is Dogtag (http://pki.fedoraproject.org/wiki/PKI_Main_Page)
woops I was meaning to comment.. not answer.
