The onboard ESP-WROOM-02 module can be programmed with any custom firmware to provide highly flexible 2.4GHz Wifi functionality. The module can for example be used to provide a data interface to the Jetson module over wifi, or to provide a Wifi beacon that transmits flight characteristics to comply with French drone laws, see e.g. https://github.com/khancyr/droneID_FR.
Flashing procedure
The module is connected over UART to the Jetson module. In normal operation this UART interface can be used to communicate between the Jetson and the ESP, but it is also used for flashing new firmware to the ESP. To do so, follow the instructions below.
- With the Open.OC 2 board powered off, bridge jumper J9, which can be found next to the ESP module.
- Power on the board, the ESP module will boot into flash-mode.
- Login to the Jetson module using ssh (or remote desktop, if it is set up)
