OpenBTS: N210 GNURadio 3.7.0
Sebaiknya menggunakan GNURadio yang terbaru untuk menjalankan N210 karena lebih mudah.
Persiapan

Test Ethernet di laptop / PC pastikan kita menggunakan Gigabit Ethernet.
WARNING: N210 hanya mau berkomunikasi dengan laptop / PC dengan Gigabit Ethernet. Jika Ethernet 10/100Mbps, maka N210 tidak mau bekerja.
Cara men-test dengan menggunakan ethtool
ethtool eth0
Harus keluar kira-kira seperti di bawah ini
Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 2 Transceiver: internal Auto-negotiation: on MDI-X: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes
Pastikan ethernet mampu bekerja pada Gbps.
Set IP address interface ethernet
ifconfig eth0 192.168.10.1
Cek sambungan ke N210.
ping 192.168.10.2
HARUS ADA Responds!!!
PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data. 64 bytes from 192.168.10.2: icmp_req=1 ttl=32 time=1.74 ms
Bagi anda yang menggunakan desktop Ubuntu sebaiknya di set juga dari Network Connection di Desktop agar menjadi IP address statik
Install SDCC
Sebaiknya jangan mengcompile dari source code karena membuat pusing kepala. Install sdcc sebaiknya langsung dari file .deb saja.
wget -c http://launchpadlibrarian.net/38703081/sdcc_2.9.0-5_amd64.deb wget -c http://launchpadlibrarian.net/38689168/sdcc-libraries_2.9.0-5_all.deb dpkg -i sdcc_2.9.0-5_amd64.deb sdcc-libraries_2.9.0-5_all.deb
