@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

Hi @Richu-Bini, The Uart Baud Rate Register (UBRR) is used to set the clock for the UART shift registers and For standard crystal and resonator frequencies, the most commonly used baud rates for asynchronous operation can be generated by using the UBRR settings provided by the AVR Datasheet: AVR306: Using the AVR USART on tinyAVR and megaAVR devices

And you can find the equation from the datasheet to calculate the UBRR values depends on the clock source it has.

megaAVR devices

Hi @kowshik1729, That was an interesting question. it can be done, but since the wifi and Bluetooth shares one radio and only one antenna, switching back and forth between wifi and Bluetooth same time while receiving packets will be difficult and cause some packet loss, but it can be done.

But instead of doing that, you can schedule two task's and switch between the task will only occupy wifi or Bluetooth. (Just a suggestion)

All of them are using Arduino IDE and it's libraries, so I think it's makes no difference.

@kowshik1729 Then go with a standard barrel jack, it can handle 6A.

How many connectors/terminal do you need? how frequently you need to disconnect and connect plug?

@kowshik1729 said in Suggestion with DC Power jacks:

easy for integration?

Thes pins can handle 6A or more and easy to use and available local shops.

What about JST Connectors?

If you are using raspberry pi as one of your main computers and have separate monitor, keyboard and mouse, then you might be tired of copy and pasting terminal commands and codes while doing projects with raspberry pi, because running chromium-browser and reading tutorial will pi slower and using a sperate keyboard and mouse use our workbench space too.

recently I read a blog Share your keyboard and mouse between computers with Barrier by Gordon Hollingworth which is cool.

In that blog, he mentioned a software called barrier, it's a software that will allow you to use a single keyboard and mouse to control multiple computers by physically turning a dial on the box to switch the machine you're controlling at any given moment. The barrier does this in software, allowing you to tell it which machine to control by moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system.

Follow these to share your computer keyboard and mouse with the raspberry pi

First, we need setup raspberry pi

Step 1: Download and Install Raspberry Pi OS on SD Card

Step 2: Connect raspberry pi to the wi-fi network

Step 3: Install barrier, for that open your terminal (Ctrl + T) and paste or enter the following

sudo apt install barrier

Then click enter.

Step 4: Setup barrier, Open barrier by typing barrier on the terminal, if you successfully installed the barrier you can see like this.

Select option Client (Use another computer's mouse and keyboard) and Select Auto config option too, also note the Screen name, which we need for the server.

That's all next we need to set up the desktop/laptop computer.

Step 5: Download and Install barrier on desktop or laptop computer (The Server), download link

Step 6: Set up the barrier by selecting Server and position your monitor on barrier software.

To Position, the screen clicks the configure server.

Here, to drag and drop the monitor icon to the desired position you need on the grid.

double click the screen and set the screen name, you can obtain the screen name from the raspberry pi barrier client. (See Step 4)

after setup, it should be like this. Then click OK

in the following screen, click Apply and Just wait few seconds then try to move the mouse to the corner. Yes, It should work.

@rafitc99 Looks cool, Thanks for sharing.
