@kowshik1729 Then I think it will be difficult, here on this video https://www.youtube.com/watch?v=po3FBdY0GS4 , bitluni's lab used CH559 USB Host controller in order to use the USB HID Services.

Another possibility is Port V-SUB to ESP32, V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR microcontrollers

I found some Github repo's that contain BLE HID

@kowshik1729 If you are using an external high-speed switch, there is only one one clock generator for both wifi and BLE and the high-speed switch you mentioned is Ultra-Wideband (UWB) 3–8 GHz from its datasheet

you also check this solution that I shared in the previous post.

@salmanfaris said in BT and WiFi Dual Core simultaneous operation using ESP32?:

There is a special option called “Software controls WiFi/ Bluetooth coexistence” it can control the ESP32's Bluetooth and Wi-Fi coexistence using software, more details: https://www.espressif.com/sites/default/files/documentation/ESP32_FAQs__EN.pdf

@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.

@rosetoby Thanks for sharing, can you post your queries with details, code snippet ..etc

Thanks for sharing @rafitc99 . Glad to know that it was solved.

@Richu-Bini I'm not sure if this is the root cause but normally, you should add an RC delay on the EN pin. This is because the BOOT pin should reach 3.3V before the EN reaches 3.3V hence, the RC delay on the EN pin. A 10K resistor and a 1μF Cap should do it. Here's a sketch on how it should look like:

Here is the part in the datasheet of the WROOM32 that tells you to do it:

@saheen_palayi Photon2 is now available at $ 17.95 on their official store page, soon it will be available on the Indian website. I was able to grab it once and will ping you once I received it.

@borncurious Okay got it. Yeah, Tez was really exciting in terms of how seamless it was. I really got astonished. when I got to know it was doing it over audio those days.

So, are you looking for any libraries to do it or any sample projects?

@zainmuhammed Oh that's cool. Let me also take a look at the stability analysis of a drone and get back to you.
