Sending file through bluetooth crontab

I want to send a file named "read.txt" using command: bluetooth-sendto. It works using the direct command on terminal "bluetooth-sendto --device=MACADDR path/to/read.txt". I want to execute it with this cron job:

*/1 * * * * bluetooth-sendto --device=MACADDR path/to/read.txt

But it doesn't work. Redirecting the output of this command results an empty file:

*/1 * * * * bluetooth-sendto --device=MACADDR path/to/read.txt>path/to/err.log

Permissions of directories and files are 777. Cronjob is settled for same user that can execute command from command line directly.

 

I need to send data between two udoo through bluetooth...

 

Can you clarify the process you're following on the receiving device, for the direct command and for the Cron job?

 

On the receiving device i'm not following any process. When I send the the file through command line it works fine and the other board receives the file.

 

The path to Read.txt is a complete path? So /home/user/udooer/read.txt

 

The path is /home/udooer/reads.txt, and that is also the path that i used. Sorry if I wrote user.

 

Also sure that crontab can find the bluetooth-sendto command? Crontab can have a different path variable than you. http://askubuntu.com/questions/23009/reasons-why-crontab-does-not-work

 

I also tried to put the command in a script and then try to launch that, but it doesn't work. I tried with other commands but I don't have this problem with them. Can still be a problem of the path?

 

From the log file of the crontab:
Jun 16 14:26:01 localhost CRON[2023]: (udooer) CMD (bluetooth-sendto --device=xx:xx:xx:xx:xx:xx /home/udooer/send.txt)
Jun 16 14:26:01 localhost CRON[2016]: (CRON) info (No MTA installed, discarding output)

 

There are other ways for two udoos to communicate with Bluetooth?

 

Bluetooth-sendto is a GUI tool, it displays a transfer dialog. Perhaps that is why it is not working with cron that has no gnome display. You could have a look at this https://hanishkvc.wordpress.com/200...mmandline-bluetooth-in-any-new-linux-distros/

 

Thank you so much. This command solve my problem: obexftp –-nopath –-noconn –-uuid none –-bluetooth <BTAddr> –-channel <OPUSHChannelNo> –put <FileToPut>.
Do you know if the channel is fixed or if it changes every time I shut down the device?

 

I have no idea, just did a quick google search to help you

 

Yesterday all worked well, now I'm getting this error:
