For the improved WiFi range and stability in challenging radio environments it is possible to add an external antenna to your Garadget.
Adding the antenna
Antenna can be purchased on eBay for about a buck shipped. Search for 2.4GHz antenna IPEX. There are many types that will work electrically, but are going to be difficult to add mechanically. One type that is easy looks like this:
It only needs a small hole in the back of the unit to get it installed:
Switching firmware to the external antenna
Next step is to upload the modified Garadget firmware that utilizes the external antenna. For that you'll need to install DFU driver. Instructions for the driver installation can be found here. The command to upload the firmware is:
dfu-util -d 2b04:d006 -a 0 -s 0x80A0000:leave -D garadget-1-8a.bin
To reverse the firmware to the original version the command is:
dfu-util -d 2b04:d006 -a 0 -s 0x80A0000:leave -D garadget-1-8.bin
