ota | universal OverTheAir firmware update system

I'm trying to get root certificate for gitlab.com so that I can download files/build artifacts from repository using GitLab API (I need this due for HTTPS authentication from an IoT device).
For GitHub, I used the following command, provided by the MCU manufacture for OTA:

I need to load a simple applet to my USIM card. Authentication is OK. I'm using OTA SMS-DELIVER via SmartCard to install CAP file.

Using these:

• https://github.com/simhacks/hello-stk.git
• https://github.com/martinpaljak/ant-javacard

I couldnt find the right spec explaining "C482XXYY" in Header.cap, how it should be calculated,

this answer below helped me navigate, but for Method.cap loading - it still fails https://community.oracle.com/tech/developers/discussion/1753814/globalpaltform-load-command-data-field

I've written this loader: https://pastebin.com/pSXeDYyS

Every component in CAP file is in separate APDU with LOAD instruction. First 5 is loaded successfully with DATA=00, SW=9000, however on Method it fails. As you can see from my script, I've fixed Descriptor size to 0000 in Directory field. And in Header C482xxyy, where xxyy is calculated properly, which is a sum of all size fields in Directory, e.g.

I am very new to React Native and Expo. I am now assigned to work on our company mobile app. While doing a build and pushing to Test Flight in Apple Connect, I noticed that my test code is getting Over the Air updated and going live. This is a big problem.

How do I tell from where my app is getting updated live?

I am using the Expo build tools. I checked the configuration for updates in the expo section of the app.json file. It looked like this:

I have installed multiple versions of .NET Sdk.Now the Omnisharp suggestions is not working fine.

output shows these

I am trying to send the 128 bytes of the block to BLE Controller using the RxAndroidBle library. the flow to send data from mobile to BLE controller is as follows

1. Connect with BLE Controller
2. Start OTA (sending 1)
3. Send CRC (of the data block)
4. Send data block
5. wait for 2 seconds
6. repeat step 3
7. END OTA (sending 2)

When I run the jq command to parse a json document from the amazon cli I have the following problem.

I’m parsing through the IP address and a tag called "Enviroment". The enviroment tag in the instance does not exist therefore it does not throw me any result.

Here's an example of the relevant output returned by the AWS CLI

I have written a Python script utilizing the Python-CAN library which records received CAN messages at a 1 second rate for 5 minutes, before logging all the messages into a file and exiting. The computer has a CAN module which is connecting to the CAN bus. (The other device on the bus is an engine) I communicate with it using the SocketCAN interface.

The test engine system that this computer is connected to is sending around 114 messages at what I believe is a 250kb baud rate. I am expecting to see 114 messages recorded in the file for each 1 second period, but instead I'm seeing about half that count. (~65 messages)

Could it be possible that the engine's ECU is set to a 500kb baud rate, and that's why I'm not getting the count I am expecting? I would think there would be no communication if the baud rates do not match, but I do not have physical access to the system because I'm sending the script remotely through an OTA update and not running it myself. (The device is headless, but is setup to run the script on startup) I just see the log files that are generated.

Here is the python code:

(A note, I have code parsing the received messages into the contained signals, but I did not include this code here because it happens at the end, and it is not relevant)

I've built an app with expo managed workflow but then we needed a native module to be added to the app so I generated native project files using expo run:[android | ios] which works well on the development but I'm curious what could be the best approach to generate android release apk for the current project?

If I follow the expo build:[android | ios] I think my native changes won't be included in that build. But at the same time if I use gradlew assembleRelease then I think I will lose the expo OTA updates.

Sorry if my question seems a mess but I really need some guidance following that approach.:

I'm trying to design an OTA update system and would like to use meta-swupdate with Yocto, here is what I did:

1. bitbake-layers add-layer ../meta-openembedded/meta-oe/

2. bitbake-layers add-layer ../meta-swupdate

3. bitbake-layer showlayers
