Re: Using Raspberry Zero as receiver dongle for bluetooth keyboards

Speaking frankly, getting hold of a secondhand USB keyboard from your local charity shop/goodwill/junk shop or an internet auction site is going to be cheaper, easier, and quicker. An example: https://www.ebuyer.com/202780-xenta-full-size-uk-layout-black-keyboard-usb-kb-6106 (no affiliation, just t...

Using Raspberry Zero as receiver dongle for bluetooth keyboards

QUESTION: RPZ has bluetooth. Also It can be switched to HID device quite easily (as far as i remember). Can i use it as HID device but not with microswitches connected to pinouts but with bluetooth keyboard? As a main-in-the-middle device which just passes trough the signals? My intuition says that ...

Using systemd-nspawn to chroot to raspberry image

Every time i create image i need to customize it and install some custom .deb package which cant be installed on original one. So i found that systemd-nspawn can be a way of chrooting into generated image. Im on Kubuntu 18.04 and i used this guide ... http://blog.oddbit.com/2016/02/07/systemd-nspawn...

Re: Boot flow and fallback system and partition

GPIO/UART is what im using daily. NOOBS is close to what i want but it needs restarts and i dont know how switching boot partitions works there. Now im dualbooting Rasbian as main OS and Alpine as upgrade OS. It has this advantage that it loads to ram. So now i can do images of whole disk. Also my g...

Re: Boot flow and fallback system and partition

Well the problem is that it is RPI Zero and the only USB (Micro) port is connected to PC. Other is for power. So USB Boot is not an option.

Partitioning and bootloader for image update on working system

In case of OpenWRT you upload image to some folder (preferable /tmp which is mountend in ram) and do sysupgrade command. In case of LibreELEC you just copy img.gz image to /storage/.update and restart the device. Ho to get similar mechanism on raspbian? I was thinking about making 2 partitions on SD...
