Hello, We are using the OveroFireStorm for a while now and its working great. The only problem is that the whole gumstix module is getting hot. With open case, the temperature reaches 78 degree Celsius after 30 minutes With closed case the Gumstix reaches 92 degree in 5 minutes I know that the Bluetooth can be turned off with echo 0 > /sys/class/gpio/gpio164/value. And I know that the Wi-Fi can be turned off with echo 0 > /sys/class/gpio/gpio16/value. Shutting down the bluetooth wins me 10 mA while shutting down the wifi wins me 250mA. The problem is that we need the wifi to connect with a wireless device. 1. Do you know why the gumstix is getting to hot? 2. Is it possible to reduce the transmit current to reduce the heating. (A wireless range of 5 meter is enough.) I've read that iwconfig should be able to do the last but it gives the following error: root@overo-maple:~# iwconfig wlan0 txpower 15dBm Error for wireless request "Set Tx Power" (8B26). 3. Should it be possible to use the iwconfig commands? I hope some of you could help me solving this problem Regards Coen |
