Hi Thomas,
I did as you said. I have 9 wires connected between my STM32F4Discovery board
and the AT86RF233 ZigBit Xplained Pro Extension board. 4 SPI wires, 3 GPIO
wires and 2 for power (+3.3V and GND).
Now doing an "ifconfig" gives me the following result:-
ifconfig
Iface 3 HWaddr: 00:00 Channel: 0 Page: 0 NID: 0x0
Long HWaddr: 00:00:00:00:00:00:00:00
TX-Power: -17dBm State: IDLE max. Retrans.: 15
Source address length: 2
Iface 4 HWaddr: 00:15:01:00:40:e4
Source address length: 6
I was expecting to see a valid HWaddr but this doesn't look right. Should I be
able to see a HWaddr if the connection is alright?
