Change FrSky ISRM Mode (EU/LBT & FCC) via LUA Script

 

Some customers of new FrSky remote controls have the problem that the internal module can no longer be flashed from EU to FCC and vice versa. This is noticeable because FrSky has sent out wrong ISRM versions to customers. Following complaints from some customers, FrSky has now provided a solution to the problem but wont publish it offically. I think the solution should be public, so I’m releasing it here on my blog.

What do we need

Step 1: install OpenTX

You have to install at least OpenTX 2.3.0 on your remote!

Step 2: check ISRM Mode

Now go to page 7/7 in your „Radio Settings“ and select „Modules RX / Version„. There you will find information about your ISRM module.

 

Step 3: install LUA Script

Download the LUA script (isrm_mode_1.lua) and copy it to your SD card in the folder „Scripts“ -> „Tools„.

 

Step 4: run LUA Script

Now go to the folder „Scripts“ -> „Tools“ and execute the LUA script (isrm_mode_1.lua). To do this, select the script and press and hold the joystick until a submenu appears. Now click on „Execute„.

 

Step 5: change ISRM Mode

You can now switch back and forth with the joystick to change the mode of your ISRM module.

 

Step 6: Check it!

Now check if the module has accepted the setting! Finished!

By the way: You don’t have to rebind your models!

    I tried with a Taranis Q x7 but it did not work, I get a syntax error.

    Is it a different lua file for each transmitter?

    Hello, I have made a small adaptation of the lua script to use it with a tool in the Horus 10X Express, if someone is trained to try it, I have only tried it in the Companion simulator, send me an email and I will send it to you.

    The error you get on a Horus X10S is: „attempt to call field ‚drawScreenTitle‘ (a nil value)“
