Re: OTA over BLE

Thanks for the reply!

At least I know I can start working on a custom firmware to do it

OTA over BLE

Hello there Espressif team!

I have an ESP32 project in ESP-IDF where I need to do OTA using BLE.

So far the examples I have found are for the Arduino framework, but not for ESP-IDF.

Is this supported by default or I'm not looking in the correct place?

Thank a lot in advance :)

DFU-OTA using ESP BLE MESH

Hello there Espressif team!

I'm using ESP-IDF to control a BLE MESH. The device is working pretty well.

I want to add OTA functionality.

The devices out of wifi range may receive the new firmware using BLE MESH? is there any example?

Thanks a lot in advance :)

DC Motor selection for vacuum pump to control with ESP32

Hello there Espressif's community! I'm working on a vacuum pump product controlled with an Arduino or ESP32. I have a working prototype but my motor seems to not reach the vacuum I need. The requirement is that the motor uses 12V DC(or 6V) and is able to produce around 80kPa vacuum pressure in a 1L ...

Encoder function hangs

Hello there! I'm working on an ESP32 in the Arduino framework with a FreeRTOS architecture. I use a task to control an MCP GPIO expander with 4 encoders working on it. The code also uses wifi, mqtt, displays, and a stepper motor. Occasionally, my encoder task is not responding, but the motor task ke...

share WiFi credentials OTA example

I'm working on an ESP32 device with OTA updates. I'm using the OTA examples in ESP-IDF and they work really well. What I want to know is how I can share the wifi credentials. At the moment the only option is using idf.py menuconfig. But if I want to set them in code or share them through BLE UART, I...

Re: problem to catch I2C interrups when using MCP23017 and adafruit SSD1306

Thanks for the quick reply! Refresh the screen at a realistic frequency is something I can implement. Unfortunately, the hardware is already done and they are on the same bus :( I tested the I2C at 1MHz and that helped catch interrupts at a faster speed than before. The interrupt is only used to inc...

problem to catch I2C interrups when using MCP23017 and adafruit SSD1306

Hello, there Espressif team! I'm working with an ESP32 in Platformio with the Arduino framework and the project works very well and as intended. The project uses 4 rotatory encoders KY040 connected to GPIO expander MCP23017 though I2C and these encoders control some variables that are printed in two...

How do I share wifi credentials over BLE MESH

Hello, there Espressif team! I'm working on an ESP BLE MESH app with the ESP32-C3. So far everything works great and I'm able to send data from a smartphone to the BLE MESH. Now, I would like to add OTA functionality. In order to do this, I need to share the wifi credentials from the smartphone with...

How do I get a unique number in ESP32?

How do I get a unique number in ESP32? Hello, there Espressif team! I'm working with the ESP32 and I would like to get a unique number on each board that I'm using. I'm using ESP.getEfuseMac() function but I already found two boards with the same number, and I have been reading several posts but I c...
