Please help me with networking using an ESP32. I use PlatformIO in VS Code for my IDE and I'd like to give my program WiFi credentials but not include the password in source control. What I'd like to consider doing is leveraging BLE on the device so that I can run a program on my Mac which would scan for BLE devices which need WiFi credentials and share with them. I'd want to write this program in Swift with Xcode on macOS. Can you help me with how to get my ESP32 to use BLE to be discoverable when so it can get WiFi credentials and also the command-line app built in Swift?
Sure, let's break this down into two main parts:
- Configuring the ESP32 to use BLE for receiving WiFi credentials.
The Arduino IDE has had a bug which causes the entire screen to go blank and become unusable. The following issues are related to this problem. It does not appear to be closed, but the upstream bug may have been fixed indirectly.
- [arduino-ide#2297]
- [arduino-ide#2148]
But if this bug is not fix, you may need to recover from the blank screen. It appears it requires killing all Arduino processes since there are some background processes which support the app. You can start by getting the process id from Activity Monitor. Filter to "Arduino" and press cmd-i to get the info. Take id and run this command with it. It is in parenthese with Process Group.
To set up a headless Raspberry Pi to connect to a Jitsi Meet server using SIP and WebRTC, you'll need the following:
-
SIP Gateway: Set up a SIP gateway for your Jitsi Meet server. Jitsi provides a component called Jigasi for this purpose. Jigasi acts as a gateway between SIP and the Jitsi Videobridge.
-
SIP Client: Install a command-line SIP client on the Raspberry Pi. Examples include Linphone or PJSUA from the PJSIP project.

- Hedy Lamarr - Known for her career in Hollywood, Lamarr was also a talented inventor. She co-invented an early version of frequency-hopping spread spectrum communication, a technology that laid the foundation for modern Wi-Fi and Bluetooth.
- Ada Lovelace - Often regarded as the first computer programmer, she worked on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine include what is now recognized as the first algorithm intended to be processed by a machine.
- Grace Hopper - A rear admiral in the U.S. Navy, she was a pioneer in computer programming and was one of the first programmers of the Harvard Mark I computer. She also developed the first compiler for a computer programming language and conceptualized the idea of machine-independent programming languages, which led to the development of COBOL.
- Edith Clarke - The first woman to earn an electrical engineering degree from MIT, Clarke invented a graphical calculator that g

Raspberry Pi 2011.12 with USB adapter for WiFi (RTL8188ETV)
If you are trying to use this USB adapter to connect your 2011.12 Raspberry Pi to connect to WiFi you may have difficulty because there is not driver preinstalled for it from the version of Linux installed using the [Raspberry Pi Imager]. What you will need is the [rtl8188eu] driver. The following instructions will get your Pi up and running on WiFi.
To check which USB adapter you have, run lsusb and see if it is an adapter from Realtek Semiconductor Corp. If it matches the name above the instructions below will help you build and install the required driver.
First, install the dependencies.
I’m setting up a workbench for working with electronics to do soldering and programming microcontrollers. Please provide a list of essential tools and supplies for my workbench.
Setting up a workbench for soldering and programming microcontrollers involves gathering a variety of tools and supplies to ensure you can tackle projects efficiently and safely. Here's a list of essential tools and supplies you might consider:
- Soldering Iron: A good quality, temperature-controlled soldering iron is crucial. Consider one with interchangeable tips for different tasks.
Please show me code which would check a server which has the new firmware along with a checksum which is then downloaded, verified and installed with fallback support. Ideally a single JSON file would list the latest release to install related to hardware models. (sent to ChatGPT)
Implementing OTA updates on an ESP32 that checks a server for new firmware, along with a checksum for verification, and then downloads, verifies, and installs it with fallback support, involves several steps. I'll provide a simplified example in Arduino code. This example assumes you have a server hosting a JSON file indicating the latest firmware and its checksum, and the firmware binary itself.
- A server hosts the firmware binary and a JSON file.
