ESP32 Arduino Core Deploy the Fleet Library

This library simplifies integration with the Deploy the Fleet update service enabling secure OTA updates. It is meant for projects that currently use the ESP32 Arduino Core library.

Requirements

• Project built using ESP32 Arduino Core library
• A Deploy the Fleet account
• Product ID from Deploy the Fleet dashboard

Usage

The library's main class implements a static getFirmwareUpdate function that checks for a firmware update from Deploy the Fleet and automatically loads it if available. It then resets the device to run the new firmware if an update occurs. You can call this function from a button press handler or other location in your project where it makes sense to trigger an update.

# define DTF_PRODUCT_ID "[YOUR PRODUCT ID]"

DTF_ESP32Update::getFirmwareUpdate(DTF_PRODUCT_ID, "[CURRENT VERSION OF YOUR FIRMWARE]");

Options

The main call to DTF_ESP32Update::getFirmwareUpdate has several default arguments defined. These additional arguments can be passed to modify some behaviors of the library. The full signature of the call is:

static DTF_UpdateResponse getFirmwareUpdate(
    const char* productId, 
    const char* currentVersion, 
    DTF_RebootOption rebootOption = DTF_RebootOption::REBOOT, 
    DTF_SetTimeOption setTimeOption = DTF_SetTimeOption::DO_NOT_SET_TIME
);   

You can change any of these options but they must be passed in the same order as defined in the signature.

Reboot Option

Default: Reboot on successful update

enum class DTF_RebootOption
{
    NO_REBOOT = 0,
    REBOOT = 1,
};

Set Time Via NTP

Default: Do not set time via NTP

enum class DTF_SetTimeOption
{
    DO_NOT_SET_TIME = 0,
    SET_TIME = 1,
};
