Hi everyone!! I am looking to develop a product where I have two ESP32 Devices communicating over BLE protocol. The goal is to display data from both ESP32s to a smartphone application. My question is, What is the best route to take? 1. Should both ESP32s publish data independently to the smartphone...

Hi, I am designing a project with esp32 DOWD bare chip, followed custom design. I have to interface external memory chip via SPI protocol. I have two questions : 1.Does ESP32-DOWD comes with Arduino Bootloader support or I will have to take some preliminary steps to get the bootloader inside the chi...

Try this approach and let me know.

ESP32 WROVER-B is compatible with Arduino IDE. The manufacturers ship it with Arduino support stored inside ROM. You might be have connection issues. You should verify.
does your board support manual or automatic bootloader configuration?

Hi everyone, I have made a custom ESP32 WROVER32 based board. I have burned basic BLE sketch onto it and have checked that it can updated over-the-air via Arduino IDE. However, I want to do firmware update over the air without using Arduino IDE. Possibly through a custom made web sever or an android...

Hi there everyone, I have made a custom PCB based on ESP32 WROVER32 Module. I want to burn Arduino Code inside the module. The sketch from the ESP32 BSP called "BLE_Server" uploads successfully but does not work. No BLE communication is initialized. Do I have to upload any bootloader inside the chip...
