HW (rev C5): 2.4G LED cannot be used
Created by: jadonk
Because the signal for this LED is the same signal as to the RF switch, it cannot be used in software. Further, it cannot reflect a valid antenna state as the signals that would enable this are not populated according to the schematic.
On the MSP430, the signal on pin 1 (P6.0/CB0) is available to control this LED. Otherwise, it is also possible to recover the signal fed to the antenna switch, since it has no valid use without the RF connection.
