I solved the problem by installing the Electrum app on my phone and then scanning the QR code. Worked first time. Thank you all

Sorry, the amount is actually .0035BTC, not .0035mBTC. Should Electrum be okay to send that amount? It won't. It just gives me the message "The server returned an error when broadcasting the transaction.
Consider trying to connect to a different server, or updating Electrum.
Transaction could not be broadcast due to dust outputs." Is there a minimum amount that Electrum will send and maybe .0035BTC is below the minimum?

I want to buy something from another country. The price they want is 0.0035mBTC. Is there no wallet that will send that amount then?

No it's not that. I'm not using version 2.3.2. I'm using the latest version which is 3.3.8. I tried installing version 2.3.2 as somebody said electrum will not send very small amounts (0.0035mBTC). I hoped the portable electrum (version 2.3.2) might let me send smaller amounts. However, I have not used it as I have no bitcoin in it. Can anyone direct me to a wallet that lets you send small amounts like the amount I mentioned above. Can you also tell me how to get my bitcoin out of Electrum and into another desktop wallet that will let me send small amounts?
I'm using the latest version of electrum which is version 3.3.8 and it will not let me send as the amount is too small.

Hi all. Please help me if you can.

I'm completely new to this and have been trying without success to send 0.0035mBTC to someone.
I constantly get the message "The server returned an error when broadcasting the transaction.
Consider trying to connect to a different server, or updating Electrum.
Transaction could not be broadcast due to dust outputs."

I tried installing the portable electrum (version 2.3.2) but can't work out how to transfer my bitcoin from the original electrum to the portable one to try sending from that. I have been trying to get this sorted for quite a while and it's driving me up the wall.
Any suggestions as to how to solve this would be most welcome.
