Banglalion Modem Running on NanoPi Neo

Banglalion Modem Running on NanoPi Neo

Recently I got a Nanopi Neo with Allwinner H3 SoC, 512MB RAM, 1 USB-A port and 1 Ethernet port. I am using Armbian as OS which is based on Debian.

I did a test if it was possible to run Banglalion WiMAX devices on this platform. So I grabbed Beceem WiMAX API sources and built it using gcc-linaro-5.2-2015.11-2-x86_64_arm-linux-gnueabihf toolchain.

First I had to build the Armbian kernel with Staging > BCM_WIMAX module. Then I dumped the image into a microsd card, put it into my NanoPi Neo and booted up.

I wasn't sure which IP it got, so I ran nmap to find it out.

root@minhaz-desktop:~# nmap -sn
Starting Nmap 6.40 ( ) at 2016-08-07 01:10 BDT
Nmap scan report for
Host is up (0.00027s latency).
MAC Address: 46:A0:87:0F:06:B6 (Unknown)
Nmap scan report for
Host is up.
Nmap done: 256 IP addresses (2 hosts up) scanned in 19.06 seconds

Then I logged into it. Checked its memory and CPU information.

I built the necessary library, daemons, clients etc which can be found at mdminhazulhaque/beceem-cscm-armv7. Let's install them.

  • Copy, and to /lib
  • Copy macxvi.cfg and macxvi200.bin to /lib/firmware
  • Copy wimaxd and wimaxc to /usr/local/bin as executable
  • Copy wimaxd.conf to /etc and change UserIdentity, UserPassword and TTLSAnonymousIdentity to your own config
  • Put bilai.pem to /etc (Use your head, ask questions or search the internet for it)

Now let's run the total setup.

  • Plug in the modem (obviously!)
  • Run wimaxd -c /etc/wimaxd.conf
  • From another terminal, run wimaxc connect 2600 10 to connect
  • If connection is established, run dhclient eth1 to lease IP from the modem (assuming that eth1 is the WiMAX device)

Here is a photo of my little buddy and the Bilai modem.
