I was unable to send the AT setup commands properly from my PIC USART to the ESP32 module. When I sent the first command it always responded with "ERROR". So I was able to modify one of my HC-05 modules to work on 3.3 VDC, and with no further setup I was able to send and receive characters at the de...

I found out how to set up the device for classic Bluetooth, and it works OK with my Android phone and the Bluetooth terminal. However, when I send an ASCII command such as "123", it responds with "+BTDATA:5,123". This was surprising, but I can easily enough parse that to get the response I need on m...

I was able to install the factory settings (bin) and the TX/RX pins work by responding to AT commands. This is on an ESP-32-WROVER module, using GPI9 and GPIO22. However, I would like to be able to use the Bluetooth function where this device acts as a wireless serial port and can be discovered and ...

That looks like a very good solution to my problems. I am familiar with the AT command codes for the HC-05, although I usually don't need to use them. Once configured, I just want to use the device as a wireless serial port to communicate with a remote PC or tablet device. I'll try implementing thes...

I plan to use one of the ESP-32 modules as a simple Bluetooth adapter that will be detected by a Win10 computer or smart phone or Android tablet, for communication between a Bluetooth terminal and my dsPIC33 project. It is a VFD motor controller and the Bluetooth connection will provide remote contr...

Does this resolve the problem with the invalid certificate that required a downgrade of the security parameters?

I was able to use one of my build configurations or projects, which I had named "blink1". I have copied the entire folder into a compressed folder but it is still about 40 Mb, and I don't think it will help, since it works, but I don't remember just how I was able to transfer it from the Public Desk...

I have only been working with the sample "Hello_World" and "blink" projects. I've only modified the main source code a little bit, and somehow I got "Hello_World" to work in Eclipse but not "blink". I really need to learn more about Eclipse which will be more convenient to edit, build, flash, and ru...

I installed the ESP-IDF suite on Windows 10 according to the information in https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html, and it somehow got installed on my C:\users\public\desktop\edf-ide-2 folder. The desktop also has the shortcut links to ESP-IDF 4.3 CMD, ESP...

Thanks for the reply. I see that my previous posts were approved, but only by logging in and looking at notifications. I had expected to receive an email as was sent when I joined. I'll see if this goes through OK, and then I'll post my current problems.
