kandi X-RAY | ESP32 Summary

ESP32 is a C library typically used in Internet of Things (IoT) applications. ESP32 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

DroneBridge enabled firmware for the popular ESP32 modules from Espressif Systems. Probably the cheapest way to communicate with your drone, UAV, UAS, ground based vehicle or whatever you may call them. Also allows for a fully transparent serial to wifi pass through with variable packet size (Continuous stream of data required). DroneBridge for ESP32 is a telemetry/low data rate only solution. There is no support for cameras connected to the ESP32 since it does not support video encoding.

            Compile errors in Tensorflow Lite Micro framework when trying to integrate Tensorflow Lite Micro to my ESP32 Arduino project
            Asked 2022-Apr-05 at 03:13

            Hi stackoverflow community,

            I am trying to get a project leveraging Tensorflow Lite Micro to run on my ESP32 using PlatformIO and the Arduino framework (not ESP-IDF). Basically, I followed the guide in this medium post https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7 and then included everything in my already existing ESP32 project.

            My project was compiling fine prior to the integration of Tensorflow Lite Micro but since integrating it, I am getting the following compile errors which seem to be related to the Tensorflow framework itself. When I uncomment everything related to Tensorflow, it compiles fine. But just when only including the following header files, it breaks:

            How to initialize a Queue on a second core of an ESP32?
            Asked 2022-Apr-03 at 12:08

            Currently I'm working on a Demo program to better understand working with FreeRTOS. Therefore I would like to try to initialize a Queue on my second core(core1). After initializing i would like to add something to it in a 1 second interval and whenever nothing happens I would like to check my queue and work its content off. Everything related to that queue should work on the second core. The reason being that I previously worked on a Webserver which operates on the main core. My future Queue is supposed to work in parallel on the second core.

            This is my current demoprogram:

            nanoFramework ESP32 Thread.Sleep weird behaviour

            ANSWER

            Answered 2022-Apr-01 at 05:39

            I think your error is that the constructor new TimeSpan(int) does not take milliseconds, but multiples of the high-resolution tick value, which is 100ns. And since Thread.Sleep() has a minimal resolution of 1ms, a timespan of less than 1ms doesn't wait at all. Therefore, as long as Ticks is less than 10.000, your loop runs as fast as it can (apparently about 3400 times per second). As soon as Ticks is larger than 10.000 (which corresponds to a wait time of 1ms) things change: Now the loop waits regularly, and you get about 100 iterations per second. This is now likely since the minimal wait time of Thread.Sleep() is 10ms (a value that varies with hardware).

            The data you provided is b'\x00\x00\x00?' - I'm going to assume that this is 0000003f (please output hex with msg1.payload.hex()).

            I'll also assume that by "float binary little endian" you mean a big endian floating point (IEE754) - note that this does not match up with the algorithm you are using (twos compliment). Plugging this input into an online tool indicates that the expected result ("Float - Big Endian (ABCD)") is 8.82818e-44 (it's worth checking with this tool; sometimes the encoding may not be what you think it is!).

            How to get a response from the async write function in capacitor-community / bluetooth-le
            Asked 2022-Mar-18 at 01:42

            I'm working with an ESP32 chip and am trying to create an Android app (using Ionic) which allows user to send wifi credentials to the ESP32 chip via BLE. I'd like to be able to update the status of the wifi sending process for the user in the UI (which I'm developing using Angular and then converting it to an Android webapp using Ionic). To do this, I'm also using the capacitor-community/bluetooth-le library.

            Can anyone explain to me what this.queue does in the async write function (code shown below) does? I thought this function returns a response from a remote BLE device after writing to a GATT characteristic, but I get absolutely nothing at all for a response.

            As a low-level C++ developer, I understand exactly what you need, and sadly, there is no replacement for flexible array members in standard C++, with or without templates. You have to keep using flexible array members via compiler extensions.

            They are not included in the language since in their current form, they are essentially a hack. They don't do well with inheritance or composition.

            The problem with templates is that, the flexible array version has a common type of arrays of all sizes. That means you can place them in arrays, have non-template functions take them as parameters etc:

            Finally, here is a work around: we are going to provide the missing /opt/osxcross folder and contents.

            1. If you do not have gcc installed (this should be unlikely though, install gcc to get the folder content, as follows: $ brew install gcc

            2. Create the missing /opt/osxcross folder as follows: $ sudo mkdir -p /opt/osxcross/target/bin/../x86_64-apple-darwin12/lib/ Note that you'll be prompted for your password.

            3. And, finally, copy the folder contents from the gcc build as follows: $ sudo cp /usr/local/Cellar/gcc/11.2.0_3/lib/gcc/11/libstdc++.6.dylib /opt/osxcross/target/x86_64-apple-darwin12/lib/libstdc++.6.dylib

            This completes the fix.

            You must restart vscode, Arduino IDE or whatever tool you use. And then build your project, which should compile successfully.

            And voila.

            I have an ESP32 T-CALL with an integrated GSM-unit and used this as a base in Arduino IDE.

            My code makes a server-call and processes the result. This code reads from the buffer and outputs it to a String. It uses a manually generated POST header, sent serially. However, I need to remove the HTTP header, leaving only the JSON.

            Answered 2022-Jan-30 at 02:01

            This is not a direct answer on how to use the regex, however, if you want to skip the headers and get the payload, other than using regex, or a httpclient library that I suggested in the comment, it is not difficult to do that without using any library.

            To skip the header and get the payload, you need to modify your code to find the end of the header.
