Baremetal ESP32

Postby Abhiram » Fri Apr 28, 2017 3:04 pm

Am a newbie in to this ESP32 platform and We are planning to use ESP32 bare metal (with out FreeRTOS), for an application which would interact with communication module like 802.15.4. (through UART) and use its internal BLE occasionally and WiFi ( for OTA). Request forums help to know if there are any limitations for ESP32 side in doing so. ( ESP32 both cores will be active )

Thanks

BT, WiFi, TCP/IP stacks all use freertos so you can't do much without it. Why u don't like it?

Agreed. All the ESP32 stacks required rely an underlying OS of some kind. Why do you have the requirement to write bare-metal stuff? If any, you may able to do the radio stuff under FreeRTOS on one core, while doing whatever needs no OS on the other one.
