What is a bootloader A bootloader is a small program running in the microcontroller to be programmed. This program allows downloading new firmware to the. Enabling the hidden Wi Fi radio on the Philips Hue Bridge 2. The Philips Hue Bridge bridges Zig. Bee 8. 02. 1. 5. 4 from compatible light bulbs to your wired Ethernet network. But it also happens to contain a built in yet disabled 8. Wi Fi radio. Is it possible to enable Wi Fi on bridge, obviating the need for a pesky Ethernet cableIn this article I will attempt to find out, with limited success. Long story short, the Wi Fi interface is fully functional, configurable within the native Linux based Open. Wrt operating system, and can indeed either act as an access point or client connecting to your local home Wi F network, but configuring the services running on the bridge to use the Wi Fi interface instead of Ethernet is trickier. Wiring up the serial port. Before we can do anything else, the bridge has to be rooted. Remove the sticky feet, unscrew using Torx T1. Microchip provides a free USBBootloader in their USB framework which is part of Microchips Applications Library. You can get it here httpwww.

Once unscrewed the case comes apart easily Solder on a 1x. J6. Note there is another serial port on J1 described by wehooper.

J9 header, not placed in production but pins shown in FCC photos. But back to J6 the hole with a square footprint on the reverse, and an arrow on the converse, is ground. Skip two pins, then the next are tx and rx. Conveniently enough, the pinout happens to be compatible with the Spark. Fun FTDI Basic Breakout 3.

If power is provided, the devices wont be damaged or at least mine wasnt, but the virtual serial port stopped responding and I had to reboot the host machine. The other pins can remain connected, just make sure GND is matched up with the ground pin indicated by the triangle on the board Fault injection to boot loader. As demonstrated in Philips Hue Bridge 2.
