[SOLVED] Bluetooth unable send file Linux PC to Android phone

Phone TETRA (Android 8.1.0) shows paired with computer dekk (Ubuntu
16.04), which shows paired with TETRA.

Dekk has two bluetooth icons: the original and that resulting from
download of Blueman.

Phone status: Bluetooth ON, Settings-Security-Location ON/High accuracy.

Trying transmit via original icon dialog. Set bluetooth ON;
"bluetooth-sendto --device=<number> <filename>" results: Bluetooth
File Transfer: Make sure that the remote device is switched on and
that it accepts Bluetooth connections.

Trying transmit via Blueman icon dialog. Turn Bluetooth On;Send Files
to Device...;Select files to send dialog: <choose file>-OK;Select
device:TETRA-OK results: Sending files via Bluetooth; Error occurred,
Unable to find service record.

My comments. I believe "paired" means having on trusted devices list,
"connected" means in active contact; meaning of "visible" (in menu of
original icon) is unknown. There seem to be other packages, such as
"hci", but Blueman seems well-documented. Google has added a bunch of
security stuff; have I missed a setting somewhere?

well I just paired my cheep android 7.1.1 using blueman, in my laptop with the 'Bluetooth devices' window open with the phone selected, that little arrow on the right hand side, I clicked it, selected 'send file' found a image then transferred it. It received it, then I turned around and sent it back from the phone to me pc. it received it too.

so I am not sure what you're doing wrong, or if it is just the phone itself.

Phone status: Bluetooth ON, Settings-Security-Location ON/High accuracy.

maybe setting Security to low or off.

I am requesting removal of this thread because I have become convinced that my laptop has a defective Bluetooth device. It is erratic as to whether it will pair with the phone, and it will never send data even when paired; whereas an older laptop will pair with the phone and send it data.

you don't need to remove it, just need to forget you even posted it.

This thread is not solved!!
In my case the error: "unable to find service record"appear, and your suggests not work.
