A couple of my students have been using the 'pdfmake' node to create a PDF version of a text-based newsletter. Another student has been using the Telegram node to send messages and photos to a mobile phone. I suggested to them... "why don't you combine what you have done?" "How about sending the PD…

Hi Dave nfs’ defines the type of filing syste, to be used should be nfs’ defines the type of filing system, to be used As to the technical aspects, I am going to give it a go.

Thanks Jeff for spotting the 'typo' (which has now been corrected on the website).

Hi Steve, A number of the students already use MQTT for their projects. The students I referred to above did initially use MQTT to transfer the PDF from one Pi to another. They then used one of my FTP Python scripts to perform the same task. It will be interesting to see and hear their reaction to…

One thing I've noticed is... if I perform a... cd /home/pi/my_mount and then a ls command in a Terminal window on the client machine, I don't see any files - which is expected. If I then mount the filing system and do another ls command, I don't see any files - not expected. In order to see the…

[image] dynamicdave: Is this normal behaviour when doing a remote mount? It is normal behaviour when doing any mount, remote or local. Think of the directory entry pi_mount as being a road junction. In the unmounted case if you drive down the road from home through the junction into my_mou…

Have you considered also showing them file sharing using sshfs ? It's a simpler process but it does rely on knowing a user password on the remote machine, so not ideal for accessing someone else's Pi, good for two pies that you own. pi@MyPi:~ $ sudo apt install sshfs ... pi@MyPi:~ $ mkdir myother…

Thanks Colin for the detailed explanation. It makes complete sense to me now. I think I'll put a paragraph in the Tutorial in case other people get tripped-up on this "effect" like I did.

Hi Bart, Thanks for your wise-words of wisdom/experience. I will certainly pass on the information to them.

Dave, did you consider using MQTT or http for file transfer? Would make a good project for your students.
