Encryption Libraries
Are there any encryption libraries that can be used with both MicroPython and Python3? The idea is to send encrypted data back and forth from the computer to an ESP32.

ESP 32 (and ESP 8266) Unstable with Powered USB Hubs
My ESP devices are unstable when plugged into my 2A powered USB hub. By unstable, I mean they eventually lose communication with my Windows 10 computer. I know the micropython program is still running because I wrote simple program to make the LED blink. The LED keeps blinking even after the communi...

Re: ESP32 crashes with Micropython with simple test program
I just got a shipment of an ESP8266. I was having the same issues with power. I plugged the 8266 directly into my computer's USB port and it seemed to fix the problem. I did the same with the ESP32 and it also worked fine. Why would the ESP's behave in this manner when plugged into the powered hub?

Re: ESP32 crashes with Micropython with simple test program
Is this a reliable board, in your opinion, to use in a production environment?

Re: ESP32 crashes with Micropython with simple test program
I did get this warning with Putty:
W (610) cpu_start: Chip revision is higher than the one configured in menuconfig . Suggest to upgrade it.

Re: ESP32 crashes with Micropython with simple test program
Thanks for the quick replies. I am running on putty now just to see it I get error messages. I should also mention that I am using a powered USB hub. I also ordered better cables. I am testing the board for possible use in a production environment and constant polling of both analog and digital pins...

ESP32 crashes with Micropython with simple test program
I made a very simple program to test my Espressif ESP32 Vroom32. The board is flashed with 10/9/19 Micropython release. I have it plugged into a Windows10 computer running Python 3.7. The board is connected to the computer via USB. It seems to eventually lose communication with the computer. The LED...
