BL V3 Update
Note: since April 2014, the boards have a version marking
Connection
For the update, three lines must be connected between the MKUSB and the BL-Board
- RXD (Pin 1)
- TXD (Pin 9)
- GND (Pin 7 or at other GND-connection on the BL-Board)
please look onto your board, where it has the 1 marking on the pin-connections
There are different possibilities to make the connections
Solution 1
- Here the GND-Pin connection is done by a simple cable
- RXD and TXD are just held onto the board (update takes only 5-10 seconds)
- GND can be connected to any GND-Connection on the BL-Board - it doesn't have to be the GND of that specific BL that you want to update
Solution 2
Here the Pins are just bended.
Solution 3
Here two pin-connectors are put in series. That creates a very convenient connector.
Update
The Koptertool is used. The procedure is similar to the FC-Update
- Power the BL-Ctrol by a DC power supply. That is better than using a Lipo, because in case of a shortcut, it might not damage the board.
- Press 'Update'
- Select the file
- Repeat the procedure for all BL-Ctrls
- After the update, the BLs will show their current version and address
