Is there a way I can update all my end devices with the same parameter in the same Application using the ttn-lw-cli without having to enter the same command for each device?

I can use the list command to get all my end device in my application but stuck on how to use the update command to set for instance _supports-32-bit-f-cnt_ to true for all the end devices without having to enter the same command one after the other for all the devices using the device id.

I tried this command:  
end-devices update my-test-stations all [flag]

I got this error:  
end device with id `all` not found in application with id `my-test-stations`

I am kind of having the same issue with end device update  
ttn-lw-cli devices downlink push   
–application-id xxxxxxx   
–device-id d54e5bffff134af8   
'{“f\_port”:6,“frm\_payload”:“AWECALQ=”,“confirmed”:true}'error:pkg/applicationserver:device\_not\_found (device `xxxxxxxx@xxxxxx` not found)  
device\_uid=2xxxxxxxx  
correlation\_xxxxxx  
I was able to confirm login via cli and list all the devices in the App also able to confirm the specific device exists  
if i use the console to send downlink with the same command it works. but i need to update 100 devices .

Ouch, ooooo, that hurts.

Device not found isn’t really the barrier to updating 100 devices, first you need to get the CLI to update one by using the documented format for the command.

And then you script it to read a file of ids to queue them one at a time - there is no bulk downlink send.

Where are these devices, I want to watch for the smoke coming out of the gateways.

Maybe smart quotes in your input JSON? Web and word docs add them sometimes.

```auto
{"f_port":6,"frm_payload":"AGE=","confirmed":true}’

```

No neither do we on the community network - confirmed downlinks are not just bad, but extra very bad - many discussions on this matter all over the forum. Hopefully you won’t end up with a perpetual downlink loop.

Yes, as I said, not formatted per the documentation.

On TTN? Maybe @rish1 can help you out.

This is changed from the previous version? Which do we fix?

Can see how it would work, but still not the documented format. If you’ve more CLI commands to use, please look at the docs.

Ouch, oh dear, end of the world, poor users in your area …
