Re: After how long do i expect the module to wear out?

I havent flashed them for at least 2 years and they were working flawlessly. I used idf v4.1 and the boards are geekreit esp32 wroom. IDF 4.1 was not even out 2 years ago. We have hundreds of modules out in the field more than 3 years old and have never had one come back. It more likely its your de...

Re: 4.3-dev OTA update speed issue.

Its been a long while for me using OTA so I don't have any specific versions. But yes I ran into the same problem. Had a project which OTA was very fast. Upgraded to a newer release and same thing for me did not change a line of code or anything else and after re-compiling and trying OTA its was rid...

Re: How long does it take for uart data to be available on RX Buffer?

@gardin. Have you looked at the many uart examples ? https://github.com/espressif/esp-idf/tree/master/examples/peripherals/uart There is more that one way to skin this cat. You can have events fire on when the uart sees certain characters. Maybe that will help. I.E. looking for CR or LF at the end o...

Re: What ESP32-S3 brings and what we can talk about ESP32-S3 and few (new ) feat.

@rudi, well written.

Can we at least know the answer to this question.
c) ESP32-S3 is Dual Core, one for APP and one for Wifi/Bluetooth, is it true?

Re: Custom PCB using multiple ESP32 devices

Kinda confused here.
I could get there with several fanout devices but that approach seems too complex and difficult to code around.
An SPI or I2C to GPIO device is far simpler than adding multiple ESP32's and trying to get all them talking to one another.

Re: Powering WS2812B-B through PNP Switch?

I looked up 2 data sheets for the WS2812B-B, both say this is a 5v device. The power range is +3.7~+5.3. Using 3.3V you are already below its power threshold. I suspect that by adding the FET it's going to drop that just a bit more to the point where it does not work at all.

Re: Increase range of BLE

Could not tell you as I do not use Bluetooth much. I can say that an external antenna will help more than the onboard one.

Re: Increase range of BLE

There are other dev kits like you have that already have the ufl connector ESP32 module on it. Just have to google around.
As an example.
