Re: WIFI/BLE Simultaneously

I agree in your point like there is some hardware limitation in which both WiFi and Bluetooth can not be operated at a time but with some workaround into software stack we can do something like that to operate both simultaneously with some hooks of software so that in real it can be considered as b...

Re: Decode url base64

Possibly because what you have is not base64 encoded; it's urlencoded.

Re: WIFI/BLE Simultaneously

What exactly means 'switching between WF and BT' ? You mean switching context? They use same host controller or something? This could be solved with different stack architecture. Again, this is not a software issue. The ESP32 only has one radio and only one antenna. This radio and antenna, if viewe...

Re: ESP32 Touch Sensing issue using SMPS

What hardware (devboards, LDO, specific SMPS, ...) are you using? Are you sure your 5V doesn't have a lot of high-frequency noise on it? I hope you're not powering the ESP32 chip directly from the 5V supply?

Re: SPI bus names

It's 'Hold' which is an input on most common SPI flash chips. (You may also run into 'WP' which is for Write Protect, which is also an input on chips like this.) SPI normally uses them if you use quad SPI mode, in which the SPI port sends/receives 4 bits at a time. You;d also need a peripheral which...

Re: WIFI/BLE Simultaneously

Sure! The difference is that these routers all work on one channel. Let me strain the analogy a bit: It effectively is as is multiple guests on the talk show are talking at the same time, but still on one radio program: because everyone interacts on the same channel and cooperates to wait for eachot...

Re: Enabling WiFi & Ethernet together

Hard to say without looking at the code. Have you tried decoding the backtrace, see where it ends up?

Re: WIFI/BLE Simultaneously

The problem is that they share a radio; in other words, while the ESP32 is sending/receiving a BT packet, it cannot listen or send a WiFi packet. It's like trying to keep up with talkshows on an old FM radio: you're switching back and forth a lot, and you can usually keep up with both because of som...

Re: Some questions about ESP32-wroom module

You may want to poke sales@espressif.com with this, as I'm unsure if the colleagues that are familiar with all the ins and outs of certifications roam these boards.
