Re: ESP32 and CR2032 battery
I'm looking at LIR2450, datasheet says max discharge current is about 200mAh, which may not be sufficient for ESP32 boot, according to ESP_Sprite post aboverudi ;-) wrote: there was tested LIR2450, CR2032 and other in parallel mode too.

Re: ESP32 and CR2032 battery
I'm looking for a possible battery options for a simple prototype, which performs the following cycle: 1. Power is on 2. Connect to WiFi 3. Send email/HTTPS request 4. Turn itself off (cut the power) Since CR2032 does not look like an option, what would be a good choice? And how many cycles (like 1-...

ESP32 and CR2032 battery
My understanding is that ESP32 should be able to run on CR2032, but I have no success with that. Trying a simple hello_world example works fine with an external 3v power source, but switching to battery a throws the following error: I (65) boot: Partition Table: I (71) boot: ## Label Usage Type ST O...

I think I just bricked ESP32
I was playing with Sparkfun ESP32 thing and then it stopped working properly. I can flash it, but any code (working applications) I try it just doesn't work. This is the log from a serial monitor, and the log is the same for any code I flash: I (2660) cpu_start: Pro cpu up. I (2695) cpu_start: Start...

ESP32 as an Access Point with the ability to store WiFi credentials (and other configurational data)
ESP32 provides a great API for managing WiFi connections and I'm looking for code example/snippets, which would allow to accomplish the following: 1. When ESP32 starts if verifies if there is any configurational data stored. 2. If there is NO configurational data, then it runs in a WiFi Access Point...

Re: HTTP requests (GET, POST etc.) on ESP32
Yes, I finally got it.. I just took a root certificate from my remote server, installed on ESP32 and now ESP32 can verify that the server is my real and indeed trusted server. Thanks!WiFive wrote: Well it can't really be secure if it is not verified, so it is just encrypted....by someone
