This is a cool idea which I'm sure will work out, however the devil is -- as always -- in the details. The golden path is easy: The main device will broadcast the OTA data to the auxiliary devices, when the devices receive the frames, they will reassemble the chunks and send it towards the OTA API....

Hello, i have a use case where i have approx. 8 ESP32S3 connected on a CANbus. My idea is to upload new firmware using one of them to open a AP, with a Websocket. This is what i have now. Then i would like the others to recieve it over the CANbus ? - the OTA dosent care where the data comes from, is...

Hello, i am runing a httpserver from a ESP32-S3, overal the functionallity is there. i have a task where i call a async send with some service information like uptime, version but also some data changing with 25 hz. The webserver can run for sometimes 1 hour, but sudddenly i get an error on : esp_er...

Hello, i have made a webserver running on the ESP32-S3, where i can update firmware. It works if i configure the device to start a softAP(WiFi). If i configure the device to run as ethernet through USB, as RNDIS device. It does not work ? Do some have experience or knowledge within this ? Here are s...

Hello, I have configured a ESP32-S3, to pop up as RNDIS device, everything works i can receive and transmit. But after i have built a web-server on top, that sends data from a websocket, some stability issues have occured. My question is, is there a way to setup a interrupt or something very fast, s...

Hello, i have a ESP32-S3, which is configured as RNDIS device, with a webserver running on 2.2.2.2. I'm trying to implement a functionallity, so i can upload new firmware via the webserver. It says OTA image has invalid magic byte (expected 0xE9, saw 0x2d). I dont know if it is possible for you guys...

Exactly. Right after tud_rx_len = size; //set tud_rx_len ONLY after finish copying you can "give" the semaphore, which makes "task" wake up and return from blocking on its semaphore "take" so that it can inspect tud_rx_len and handle the data. Okay i have tried looking at this, but i cant seem to u...

Exactly.

Right after

Code: Select all

tud_rx_len = size; //set tud_rx_len ONLY after finish copying

you can "give" the semaphore, which makes "task" wake up and return from blocking on its semaphore "take" so that it can inspect tud_rx_len and handle the data.

Perfect, ill try that. I appriciate your time !

vTaskDelay( 1 / portTICK_PERIOD_MS ); may be part of your problem. Note that by default the tick period is 10ms, so any delay of less than 10ms results in a 0 delay, which can starve lower priority tasks of CPU time which then may fail to reset their watchdogs in time. Besides, polling on the tud_r...

<r>Hello, i have a question regarding a error where it looks like the watchdog is getting triggered from a usb descriptor or from a http webserver.<br/> Im working on a project, where a ESP32-S3 is configured to pop up as a RNDIS device when it's plugged in to the computer. THe device is set to a IP...
