v1.0.0

The sd card image split into several parts because the host limitted the largest file size.

The following instrustions assumes:

To download and join the parts under Linux (about 152.1MB)
Your Raspberry Pi sd card is the device ‘/dev/mmcblk0’ (change the device name according to your system)

Download rpi.img.xz.part00~rpi.img.xz.part02 to a directory
In the above directory, join the parts together
```
  $ cat rpi.img.xz.* > rpi.img.xz
```

Write sd card

  $ sudo sh -c 'xzcat rpi.img.xz > /dev/mmcblk0'
  $ sync

Plug the sd card to Raspberry Pi, power on. It is for Raspberry Pi 3 only (all models)

This image enabled hotspot AP by default, on your ground control station, search ssid bithollow-bh, default password is bithollow. Its dhcp server have only one available client ip in the pool: 10.0.0.2, lease time 1 day.

If you try to connect more than one client, only the first one can get the ip. Even you disconnected the first client, before the lease time expired, other clients wouldn’t be able to acquire the ip address as well. If that’s the case, try set static ip 10.0.0.2, netmask 255.255.255.0 to your client computer.
To config the hotspot AP, access 10.0.0.1 in your web broswer, user: bit, password: hollow
While trying to connect uart on Raspberry Pi, turn off GPS power by the DIP switch on BH board. GPS occupied this uart, if it is power on, you will see garble in the uart terminal. (more information about the DIP switch is in user documents)
