Unfortunately, I don’t think that’s practical for inclusion as a PR at the moment for the reasons provided in the linked topic. If you’re willing to build your own firmware, you could write a custom binding to transfer 3 bytes. Though even an attiny10 (6 pin SOT23-6 package) should be able to do it, I’d still have to “split” the I2C bus with all the support circuitry, while I’d rather have the flight controller do the work. That’s what I wanted to avoid since I’m literally one byte away from a solution. Otherwise you may be stuck using an intermediate microcontroller to interpret scripted messages and send sensor values back. Unfortunately it is stored in volatile memory only. If the address is stored in non-volatile memory, you might try connecting it to another device like an Arduino or ESP board, writing the address, and then using it with your script. I tried that already, but as expected it does not work. What happens there (de-duplication, versioning, overwriting with or without prompting) would be up to you, within the constraints imposed by the iOS SDK, which I know nothing about.At the moment, I don’t think you can send three consecutive bytes like that (though maybe two consecutive writeregister calls may be interpreted by the device that way - I kind of doubt it). lua files, the editor can later copy the edited file back to your app’s sandbox. If the receiving editor implements “Open in” too, and your app has registered as being able to edit. ![]() I’m hazy as to implementation details, not being an iOS dev myself, but if the rules of UTI declaration from OS X and some stuff I have observed while using my iDevices holds true, you can even insert the file type into the public.text UTI hierarchy in your own app, which will add support for it to all text editors on the device. lua documents via this mechanism, any text editor recognizing the file type can receive a copy into its own sandbox. If your app implements the ability to forward its. It is however possible to “pass” files from app sandbox to app sandbox (strictly speaking: to copy them) via the “Open In” mechanism supported since iOS 3.2, as seen when opening Mail attachments in other apps. This means that in iOS, it is not possible to edit one and the same physical copy of a file in multiple applications, as every app needs a copy in its own sandbox. The cross-application file layer does not exist in iOS. TextEdit sees the document being located in its sandbox – ~/Library/Containers//Data/Desktop, but it is also clearly saved onto your desktop ~/Desktop – at the same time both directories are, for the purpose of the sandbox, one. You can plainly and pretty simply see that for yourself by editing a text document on your desktop in Lion’s TextEdit. As correctly stated this will not work as straightforwardly as expected on a desktop (or more permissive mobile) OS due to iOS sandboxing model, which effectively constrains application data to the application itself, although it is worth noting the issue at hand is not the sandboxing per se, which also exists in newer versions of OS X, but the fact iOS offers no unifying file system layer which is mirrored into applications’ sandboxes.
