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:

Your loop should not use feof to test for end-of-file because the end-of-file indicator is set only after the end is reached. It cannot tell you in advance there is not another character to get.

Looking at your loop, I suspect you do not need to “go back” in the file. You just need to read one character and examine it in multiple ways. To do that, you can simply read the character and assign its value to a variable. Then you can use the variable multiple times without rereading the character. For future reference, when you do want to reject a character, you can “put it back” into the stream with ungetc(c, dat);.

Further, I suspect you want to read each character in the file and characterize it. So you want a loop to read through the file until the end. To do this, you can use:

To read one character, test it, and reject it if it is not satisfactory, use:

QUESTION

ESP32 Flash Encryption

Asked 2021-Nov-13 at 20:32

Working on implementing flash encryption and secure boot on ESP32. The first step is to get flash encryption working. I am targeting the following settings:

Release Mode
No reflash over UART.
Use the esp generated key (no need to reflash anything).

MAlong with my 2 OTA app partitions, I have used a data partition of sub-type nvs to store my device security certificate for access to my cloud backend.

In my partitions.csv file, I don't think I can set the nvs partition to encrypted as it would brick my device. How can this be made secure?

Do I need to add nvs encryption an nvs_keys partition?

...

ANSWER

Answered 2021-Nov-13 at 20:32

NVS partitions can also be encrypted, but it's done differently from encrypting everything else in Flash. In short, you need two partitions. One is your NVS data partition which gets encrypted using NVS encryption algorithm. Other is the "NVS keys" partition which holds the encryption keys for previous, and this one gets encrypted using the standard Flash encryption algorithm. If it sounds confusing, welcome to the club. But once you dig through this, it works fine.

Pre-generating an encrypted NVS data partition with some data on it (e.g. your certificate) now gets an extra step where you encrypt it on your computer before writing it to Flash.

ESP-IDF wifi event loop keeps receiving SYSTEM_EVENT_STA_WPS_ER_PIN even after code rollback

Asked 2021-Jun-01 at 20:46

I have been working on a project using the ESP32 with the ESP-IDF that will check it's NVS memory for wifi credentials before starting the network stack. If it has said credentials, it will connect to the wifi network in STA mode, if it lacks them, it will launch as it's own AP to allow the user to send it the credentials over HTTP.

After manually putting my test credentials into NVS, I started working on the AP code. Once all the AP code and logic was complete, I manually wiped the flash memory with esptool to force the board to launch in that mode. Doing so worked fine, and I was able to send it the updated credentials over HTTP.

At this point, the board attempted to connect as STA upon reset, however, the SYSTEM_EVENT_STA_WPS_ER_PIN event kept being caught by the wifi event loop. The board has since only experienced this event and has been completely unable to connect to wifi since. To make matters stranger, even after rolling back to a previous version with git, the problem still persists.

Switch WiFi mode from AP to STA

Asked 2021-Apr-27 at 14:51

I'm working on project with ESP32-S2-Saola-1M board in C/C++ via ESP-IDF framework. At the beginning I initialize a Wi-Fi in an AP mode and starts the HTTP WebServer to get WiFi data from user through browser. After the user saves his Wi-Fi data (SSID and Passwd) throught page, the HTTP server should shut down and Wi-Fi switch from AP mode to STA mode - connect to user's Wi-Fi. I have problem with this part. I don't know how to solve this elegantly and in principle correctly. So can someone describe me any solutions or better ideas please?

I thought of using method with while cycle and POST handler. After the data comes from page via POST request, handler saves them and set some bool property (e.g. hasData in code below) to true and while cycle in method breaks/stops and other code in application can continue. Something like semaphore. Simply:

start Wi-Fi (AP mode)
start webserver
wait until user sends his Wi-Fi data
stop webserver
stop Wi-Fi AP mode -> switch to STA mode
next actions... (measure, send data out, deep sleep etc.)

By far the easiest approach is to just reboot (esp_restart()) after saving new configuration.

Then select the right mode after reading the configuration on boot.

It looks like you DNS server is not resolving the fqdn to an IP address for some reason.

run print(wlan.ifconfig()) to check your assigned DNS server in the last nibble
check if your DNS server perhaps is configured to filter queries from the specific client / subnet
resolve the FQDN to IP on a different client (your PC) , and use that IP address in MicroPython. If that works your DNS is the problem
you can also test your DNS using :

Visual Studio Code can use NVS to select a node version to use when launching or debugging. In launch.json (in the folder .vscode located on the project's root folder), add a "runtimeArgs" attribute with an NVS version string and a "runtimeExecutable" attribute that refers to nvs.cmd (Windows) or nvs (Mac, Linux).
