JN5148 High-Power USB Dongle (DR1131) Reference Manual 2.5 High-Power Front-End The front-end is a Skyworks SE2431L. This means that the dongle can achieve 22dBm output power and Rx sensitivity of -100dBm. The output of the front-end is connected to a printed antenna. 2.
JN5148 High-Power USB Dongle (DR1131) Reference Manual 3 Programming the LPC1343 Device The LPC1343 device is supplied pre-programmed on all USB dongles. You should never need to reprogram the firmware in the LPC1343 device when developing applications for the JN5148 device. If you are producing new USB dongles or are developing new ways to communicate with the JN5148 device (i.e. new HID classes) then the mechanism for reprogramming the LPC1343 is as follows. 1.
JN5148 High-Power USB Dongle (DR1131) Reference Manual 4 Programming the JN5148 Device 4.1 Re-programming USB Dongles You can easily re-programme a dongle with another binary file through a USB port of your PC and the LPC1343 device on the dongle. The replacement binary file must be a specially prepared file called FIRMWARE.BIN.
JN5148 High-Power USB Dongle (DR1131) Reference Manual 4.4 Installing Device Driver for USB Dongle 1. The first time you plug the dongle into a USB port of your PC, an ‘Installing driver’ message appears in the bottom-right corner of the screen. The system will install most of the software required, but will leave the following box: 2. Close the box and go to Start > Control Panel > System > Device Manager.
