The ESP device supports the OTAU cluster as the server and will be used to update
The ESP device supports the OTAU cluster as the server and will be used to update
other devices. For this purpose, the ESP is connected to a PC serially. The
Bootloader PC tool from the Serial Bootloader package transfers the provided
application image to the ESP, which distributes it to other devices. In this case use
the ‘Passive’ mode in the Bootloader PC tool.
Another scenario is also possible: a device programmed with the Runner application
Another scenario is also possible: a device programmed with the Runner application
is used as the OTAU server. This ‘Active’ mode shall be used in the Bootloader PC
tool. The user shall select one of the networks discovered by the Runner device and
specify security information for the network.
