Re: ncrease Bluetooth power

I do not think there is. I've just had a look at hciconfig and the only thing I can see on 'power level' is: inqtpl [level] Get/Set inquiry transmit power level Thank you. What about an hardware solution to extend a wire (antenna) outside the box? I have my Rasberry installed into a metallic case w...

Re: ncrease Bluetooth power

Isn't there any other way to increase the BY range, unless adding an external trasmitter?

try adding a self powered USB bluetooth adapter
Hi, thanks for answering. That device is really interesting, but I was looking for a way to use the internal Bluetooth, without adding more complexity.

ncrease Bluetooth power

Hi all,

is there any way to increase TX bluetooth power? I am using Raspi to stream music to a bluetooth speaker, but am experiencing a maximum range of 5-6 meters.

Re: WiFi Connection manager with fallback web configuration portal

From what I've read nobody who has coded this type of system for the Raspberry Pi has released it as free software. While I'm guilty of that too, the following exists and might be what OP is looking for: https://github.com/balena-io/wifi-connect Hey, that's EXACTLY what I was looking for. Great! Yo...

WiFi Connection manager with fallback web configuration portal

I have realized an unmanned embedded project with Raspberry which works on WiFi. Now, in order to let it really flexible and portable, I need an easy way to choose the WiFi AP to connect to, without the need to access to the SD or other "acrobatic" processes (ethernet/video/keyboard). With Arduino/E...

Hi all, I am running udisks (with automount udisks-glue) on a Raspbian Stretch system and I would like to migrate to udisks2, as I have read that udisks is becoming obsolete. The only document that I have found is related to Ubuntu "snap" system, which does not apply on Debian Stretch. Any tip? Than...

Re: Is it reliable to backup Raspi from remote?

In embedded systems one usually don't need full system backups. Correct, "usually", but that's not my case. The usual solution to the problem of having your storage in an indeterminate state is to keep temporary files in RAM and to synchronize them to storage on a schedule. This also helps keep fla...

Re: Is it reliable to backup Raspi from remote?

@rln: So, in other words, there's no way to backup a Raspberry embedded in a big project without stopping everything, unscrew, unplug connectors and remove the raspberry in order to get access to the SD card?
If it's true, Raspi should not be so popular.

Re: Is it reliable to backup Raspi from remote?

I want to thank you all, giving me suggestions for backup code, but maybe my first post in the thread was not clear, sorry. I perfectly know how to backup a partition, a whole device, etc. What I am asking (maybe to myself) is: is it reliable to hot backup a live and working block device ? Thank you...

Re: Is it reliable to backup Raspi from remote?

I have checked the cli version and it is using dd without unmounting devices.
I don’t want to install a GUI as it is not needed in the project and I don’t like GUIs for embedded scopes.

Re: Is it reliable to backup Raspi from remote?

Although PINN is primarily an os-installer/boot-manager, you can also hide PINN so you don't even know it is there in normal use. When you want to perform a remote backup, you could enable it, do the backup and then hide it again. It only takes up about 60MB of your SD card. I will investigate this...

Re: Is it reliable to backup Raspi from remote?

@B.Goode
Thanks for your reply. I don’t know how SDCardCopier works as I do not have a GUI, but I have investigated other cli tools and all of then make a brutal dd copy of the whole SD, so I believe the GUI tool acts the same way.

You probably would either have to code, or use software, or manually VNC into the Pi and backup to a SMB share.
I have ssh accesso to the Raspi, that's not the point.

Is it reliable to backup Raspi from remote?

I have seen many posts and "howto" concerning backing up Raspi's SD from remote, with the use of dd on the main mmcbl0 device (which has 2 partitions inside). As an old time LInux user, I know how unreliable is it to backup mounted and running partitions: services, /sys, /proc, etc... I mean, you CA...
