Re: Investigating delta OTA update via LoRa
Is that 26KB difference between the binaries , or is 26KB the size of the resulting (compressed) patch file?
I'm not doing yet the "patcher" , I am in the process of checking whether it is a viable option.
There are 26000 differents bytes, some of them in a row but most of them are isolated and ...

Investigating delta OTA update via LoRa
I was thinking about building a custom delta update system for OTA via LoRa (1-5 Kbps), super optimized for patch size, sending absolutely the bare minimum necessary.
I just did a test with a basic firmware that takes up 280KB.
void setup() {
Serial.begin(115200);
Serial.println("Hello from ...

Re: ESP32 Delay circuit for EN pin
you could use a Reset Supervisor for the EN pin. They also come in through hole versions as well.

Thanks for the recommendation, I will take note. Unfortunately I already have the board finished and have no ...

ESP32 Delay circuit for EN pin
Hi there,
I have some problems with the power supply (which I can't change) which is quite weak at the first start-up.
ESP32 often resets several times at startup until the power supply stabilises. I have measured that by adding 10k/20uF for EN pin, the ESP32 startup/power demand is delayed by ...

Re: ESP lowest consumption module recommendation
If you haven't already, check out light sleep mode; there's also an "automatic light sleep" option with which light-sleeping can work pretty much invisibly in the "background" whenever the chip has nothing to do for a few dozen milliseconds or longer.
Thanks for that tip, I was no aware about ...

Re: ESP lowest consumption module recommendation
Using the RISC-V ULP of an ESP32-S3 may be worth looking into.
Thanks for the info. I didn't know that feature, however as I'm using a general purpose code (spi, great memory arrays, i2c, gpios, loops etc..) not sure if ULP can handle that.
ESP32-S2 is the most suitable candidate ...

ESP lowest consumption module recommendation
Hi There
I have to do a low power project (cpu always running, don't care sleep) with 15 GPIO and I want to keep using ESP as I love these chips and I am familiar with them. the project it's currently working on a esp32-WROOM-32E @ 10 Mhz , drawing (just the wroom module) ~13mA while running the ...

Re: Best practices for USB Vendor / Product ID
Understood!!I'm the guy who hands out the PIDs there. If you make any number (>=1) of devices you give away or sell or whatever, as long as you're willing to answer the questions in the readme of that repo, you'll get a PID.
Thanks

Re: Best practices for USB Vendor / Product ID
Not sure if I can bother them for a very low quantity product, that's why I was asking if the serial number could be a solution

Re: Best practices for USB Vendor / Product ID
Yeah, I already mention that link in my original post, do you mean to write to Espressif to create a new PID?
