esp32

This is about how to exchange AES256 encrypted messages incl. generated IV (initialization vector) between a ESP32 and B4x. Notes: - the ESP uses AES/CBC/NoPadding. The data must be padded (must have a length which is a multiple of 16). I've used a length of 256 to to get there (instead of...

Finally I got it working. Maybe the Inline C code is not that elegant :) I was too lazy to add a Salt (which I will update later). Hardest part (for me as I don't like C since the 90ies) was to exchange the data between B4R Main and the Inline C. However: I got it. Note: As PKCSNoPadding ist...

I've found examples in C but I'm not experienced with inline C. Could someone adapt these examples to usable inline code? RSA https://github.com/espressif/arduino-esp32/blob/master/tools/sdk/include/mbedtls/mbedtls/rsa.h AES...

Following these instructions you have access to the 3 hardware serials on an ESP32. Serial0 is connected to the USB interface. The default pins are Serial0 - RX: GPIO3 , TX: GPIO1 Serial1 - RX: GPIO9 , TX: GPIO10 Serial2 - RX: GPIO16 , TX: GPIO17 On a TTGO Lora board the GPIO 9,10,16,17 are...

On the ESP32 the following code increases allocated RAM about 500 bytes each iteration until it runs out of RAM. Am I missing something? SKIP_B4RNEW doesn't make a difference. Library version is 1.10. #Region Project Attributes #AutoFlushLogs: True #CheckArrayBounds: True...

Hallo, ich komme irgendwie nicht weiter. Ich versuche über einen ESP32 eine 4 Kanal Relaiskarte anzusteuern. B4A bringt die Schaltbuttons auf ein Smartphone. Hat das schon jemand gemacht?

I'm sure some of you have seen some of the youtube clips of the ESP32 Camera Module (if not you can check out a few here). The demos are intriguing and open up a world of possibilities. I have a project in mind to use an ESP32 and the Camera module triggered from a PIR sensor and snap a picture...

The Arduino IDE can only install one of the ESP32 or ESP8266. However, the ESP32 library of B4R depends on WIFI. H, and some of them depend on ESP8266WIFI. H. How do you make both ESP32 and ESP8266 compatible It is recommended that ESP32 be built separately

The latest firmware for the ESP32/WROOM32 adds many new possibilities over the ESP8266. e.g. being able to specify DNS servers. Are there any plans to provide a library for this? I'd be happy to make a donation towards the development :) Thanks, M.

Can I communicate with cellphone through bluetooth with ESP32 ? It´s already implemented ? Thanks
