Hi, I have an older FLARM in my glider and found some issues last weekend while flying. I'd like to update the firmware but I can't find any detailed guide to follow.
So far I have found this guide:
https://support.flarm.com/hc/en-us/articles/360002205694-How-do-I-update-the-Firmware-on-a-Classic-FLARM-without-an-SD-card-slot-
Only issue I have is how to connect it. I have a serial to USB cable but the next requirement is "A cable connecting the RS-232 adapter with the FLARM device"
Does that mean I need a console cable (rs-232 to rj45) as well?
If anyone has some more details on how to connect it, would be greatly appreciated!

the
pinouts for rj45. The power uses the outside pins 1/2 and 7/8 check
polarity
and it give data in and out wired to Dsub to connect to USB to serial
interface
cable.
So you need to split the cable on the rj45 to access power and data.
I made my own from this manual. You can also buy ready-made cable unit at
some cost.

It gives pinouts from RJ 45 and also data pinout to 9 pin Dsub.
So if you use a ready made 8 way cable with a RJ 45 connector each end, cut
one end off open up the cable and separate the individual wires. Use a
meter to
confirm pinouts of power and data from image in manual, power is 12 v, make
sure you have correct polarity, and wire the three wires used for data to 9
pin
Dsub.
Download the flarm tool listed on flarm.com website for updating without SD
card and install on laptop, windows, not apple!
Connect your homemade cable to USB serial adapter and power the flarm.
Choose serial port, may not be the one first offered(1) may be 3.
You may have to go into control panel, device manager, ports and alter
baud
rate. If you get correct port and baud rate you will notice it says connect
to
flarm.

You've mentioned a ready-made cable, would you happen to know where it can be purchased?

You've had some really excellent explanations of the procedure.
I just wish to draw your attention to the settings.
The Flarmtool software lets you set the Flarm's parameters and communication settings.
I usually find that my preferred settings are overwritten by default every time I update the firmware.
My preferences are:
. max permissible H range
. max permissible V range
. competition mode (less alarms)
. 19200 com speed.
. Position+traffic info active on external port (GPS+Flarm sentences) (if not, you won't be able to connect to external instruments and viewers)
Definitely worth checking. After the update has been completed, disconnect and then reconnect your Flarm, use Flarmtool, explore and adjust the settings. This will save you the time to troubleshoot all your connections and then redoing the Flarmtool procedure.
