FollowMe
This is a description, how to build a FollowMe-Transmitter.
For the connection between the FollowME and the Kopter you need a Bluetoothmodul or if you need a bigger range, a Wi.232 Modul.
Bluetooth-Module:
At the MikroKopter: The jumper on the Bluetooth-Modul for the Kopter must be set correct (S1: 1-2 / S2: 2-3).
At the FollowMe: The jumper on the Bluetooth-Modul for theFollowMe must be set as for a use on a PC (S1: 2-3 / S2: 1-2).
You have to pair booth Bluetooth-Modules (Link).
Wi.232-Module:
At the MikroKopter: The jumper on the Wi.232h-Modul for the Kopter must be set correct (S1: 1-2 / S2: 2-3).
At the FollowMe: The jumper on the Wi.232h-Modul for theFollowMe must be set as for a use on a PC (S1: 2-3 / S2: 1-2).
Booth Wi.232-Module have to be programmed correct: (Link)
Kopter= Slave
PC or FollowMe= Master.
FollowMe: What is this
A effectful feature to let the MK automatically follow you like on a dog leash.

Attention: The FollowMe sends Waypoints to the Kopter. So this will work in the GPS-Radius of 250m of the NaviCtrl on the Kopter (around the Startpoint).

Stand-Alone: the follow-me transmitter is self-power supplied to put it in your pocket

Note: it only works in the 250m GPS-range (measured from the starting point)
How does it work?
The Follow-ME-transmitter sends its own position 5 times per second as the target position of the MKs.
In the NaviCtrl (on the FollowMe-Transmitter) a special firmware version is needed.
The NaviCtrl sends the position data simultaneously on the 10-pin "debug" interface and also on the 10-pin "flight control" interface.
The Bluetooth transmitter (or Wi232) you normally use on the PC, is connected on the NaviCtrl (on the FollowMe-Transmitter) on the "FlightControl" interface.

Example 2: |
Example 1 with NaviCtrl 1.1
What you need
A NaviControl 1.1
- A MKGPS version 1.0 or 2.1
- A Lipo and Deans plug
- A 5V voltage regulator or Recom
- A Bluetooth or Wi232 wireless transmission
Step 1: Solder the voltage regulator
On the Navicontrol there are soldering pads for a SMD-5V-Voltage regulator. You can also use a 5V-Recom, as described on the photo.
Note: Solder all three pins - especially the GND pin (large pad) is very important.
Step 2: Solder the supply line
The FollowMe-Transmitter is supplied by a Lipo. It works with a voltage of 7.5 - 16V
Step 3: Install bridge
Connect the pins "5V" and "5V Servo" on the NC.
Step 4: Software
On the NaviControl of the FollowMe a specific software needed. On the MK the current version (eg, NC 0.22) remains in use and will not be changed.
Software: Download - FollowMe-Software
NOTE: This particular version does not work for navigation on the MK - The Koptertool will report "Incompatible" or "! FollowMe only !" after importing the version - this can be ignored
Step 5: Wireless Link
The FollowMe transmitter and the NaviCtrl at the MK are connected to each other via two Bluetooth modules (or Wi232) .
- On the ground: The Bluetooth module that is normally used on the PC (MKUSB) comes to the "flight control" interface (SV8.
at the MK: The Bluetooth module remains as usual on the Debug Interface of the NaviCtrl.
Note:The Bluetooth module on the FollowMe-NC is connected to the interface that normally goes to the flight control! (Otherwise we would have to change the jumpers on the Bluetooth module)
The jumpers on the Bluetooth modules remain exactly as they would be used on a MKUSB
Step 6: Test and application
The green LED on the GPS of the FollowMe starts flashing as soon as it starts to send the position data. (5 times per second when the GPS has enough satellites)
The MikroKopter beeps for each received position record.
Bevor you start your Kopter this must have a satfix too. After this you can fly with it and switch the GPS-Switch to "CH" (on the Following-MK). The MK should now following the FollowMe-transmitter.

Example 2 with NaviCtrl 2.0
What you need
A NaviControl 2.0
- A MKGPS version 1.0 or 2.1
- A 9V Block battery and connector cable
- A 5V voltage regulator or Recom
- A Bluetooth or Wi232 wireless transmission
Step 1: Solder the voltage regulator
On the NaviCtrl 2.0 there are soldering pads for a 5V-Recom. This can be installed from the bottom.
Step 2: Solder the supply line and the bridge
The FollowMe-Transmitter is supplied in this example by a 9V Block battery. You can solder the cable for the battery cable
on the upperside beside the solderings of the Recom (see picture).
Also you have to bridge the pins "+5V" und "+5V Servo".
Step 3: Software
On the NaviControl of the FollowMe a specific software needed. On the MK the current version (eg, NC 0.22) remains in use and will not be changed.
Software: Download - FollowMe-Software
NOTE: This particular version does not work for navigation on the MK - The Koptertool will report "Incompatible" or "! FollowMe only !" after importing the version - this can be ignored
Step 4: Wireless Link
The FollowMe transmitter and the NC at MK are connected to each other via two Bluetooth modules (or Wi232) .
- On the ground: the Bluetooth module that is normally used on the PC (MKUSB) comes to the "flight control" interface (SV8)
at the MK: The Bluetooth module remains as usual on the Debug Interface of the NaviCtrl.
Step 5: Test and application
The green LED on the GPS of the FollowMe starts flashing as soon as it starts to send the position data. (5 times per second when the GPS has enough satellites)
The MikroKopter beeps for each received position record.
Bevor you start your Kopter this must have a satfix too. After this you can fly with it and switch the GPS-Switch to "CH" (on the Following-MK). The MK should now following the FollowMe-transmitter.

Replica Version: two MKs
what you need
a MikroKopter with NaviCtrl and GPS
a second MK with NC and MKGPS as FollowMe-transmitter
- one Bluetooth- or Wi232-Transmission
Step 1: change software on the FollowMe-transmitter-NaviCtrl
The transmitter MK needs a modified NC-Software. This software simply sendt its own position to the second MK. The Version of the flying (following) MK doesn't have to be changed.
Software: Download - FollowMe-Software
This firmware also sends POI-coordinates (since NC Version 0.24) - see also: Firmware-0.84
NOTE: This particular versions do not work for navigation on the MK - The Koptertool will report "Incompatible" after importing the version - this can be ignored
Step 2: Wireless Link
The FollowMe transmitter and the NC at MK are connected to each other via two Bluetooth modules (or Wi232) .
Transmitting-MK: Remove the 10pin cable between the NaviCtrl and the FlightCtrl. The 6-pin cable between the FC and NC-MK remains connected and is only for power supply of the NC. The Bluetooth-module (or wi232) that is normally on the PC (MKUSB) is used on the "flight control" interface (SV8) of the NaviCtrl on the transmitting MK.
- at the MK: The Bluetooth module remains as usual on the Debug Interface.
Note:The Bluetooth module on the FollowMe-NC is connected to the interface that normally goes to the flight control! (Otherwise we would have to change the jumpers on the Bluetooth module)
The jumpers on the Bluetooth modules remain exactly as they would be used on a MKUSB
Step 3: Test and application
The green LED on the GPS of the FollowMe on the Transmitting-MK starts flashing as soon as it starts to send the position data. (5 times per second when the GPS has enough satellites)
The second MikroKopter beeps for each received position record.
Bevor you start your following Kopter this must have a satfix too. After this you can fly with it and switch the GPS-Switch to "CH" (on the Following-MK). The MK should now following the FollowMe-transmitter.

A GpsShield on the FollowMe-transmitter can help to get a better reception.
