Hello, https://templates.blakadder.com/T-01C3.html I want to use an ESP01-C3 as in the above link for Bluetooth connection to Android ( BT Classic) from an Arduino. As it comes there is no BT support and you get the "Bluetooth is not enabled! Please run `make menuconfig`" message which it took me so...

Hi All After a whole day yesterday of debugging finally got my code to run and connect to an Android via BT, so around 3pm I decided to leave on soak test overnight. In the morning IT had died. IT is a esp32 Wroom32U with an FTDI serial on my own board. In various versions Ive had the same basic ver...

Thanks for the explanation, that makes sense. What I was hoping was that there might be some information as to what caused the crash, rather than how to recover from it. I'm not overly worried about saving this particular chip. I did ask if there was any other way of logging exceptions other than a ...

Hello Sprite, I'm sorry but I dont understand. Could you please explain how you have concluded that it happened early in the process. As I said in my first post that the unit had operated successfully for several hours before being left powered up, but unconnected for a period. I also have 4 other i...

Well thanks for trying Sprite, I'm really a little unsure of how to proceed. If I assume that the fault is not solder splashes corrupting the flash then is there a mechanism that the software can self destroy? An exception error as I understand it says 'you had a problem, here it is and stops' but y...

Hello Sprite, I'm fairly new to ESP32, and have only been using Arduino IDE, so no I haven't tried erasing chip, I guess that's going to involve me getting familiar with the Flash Tool, which I will certainly look at today. What I mean by 'appeared to work' is that it established connection and went...

Hi Sprite, and thank you for your suggestion. I've gone over the board with a magnifier very carefully, there are only pads on 17-22, I can't see any solder whiskers. I probably programmed this particular board 20plus times during development without a hitch, as well as several weeks testing before ...

Hi, I do hope some kind soul can help. I have a custom board with a WROOM32 module and FTDI serial wired as per devkit C for booting. Everything runs and loads etc fine. The board is powered by a 5v supply, not USB, and is used to read various encoders and output the data normally just via BT to an ...

Hi Mike,
No Im using a Devkit C bought from Mouser, so hopefully the real thing. My original one was from ebay, so origin unknown Found that was cheaper than making my own.
Thanks for your interest

Steve

Hello I am using Arduino IDE on Visual Studio 2019 with Visual Micro ( but same in standard IDE). I have some code which was working ok on breadboard with an old ESPdevkit I had. Ive now made some PCB and bought some new Devkit C modules. After programming the unit worked as expected, but having unp...
