@haythem Thanks for your contribution! Your Youtube work is also very good stuff.

@jossvall I wonder if removing the mmc kernel module would solve this issue without the need to modify your hardware design this late in the game.

@jossvall opkg install pciutils

@Zemlak How did you install python 3.6

@Russell-Pirie "...will they all fit??...." You'd need to be specific as to what they are and how they are configured in order to answer that.

I'm not sure you need to rewrite a bluetooth driver, most users would utilise "Bluez" package for bluetooth, perhaps take a look at that package and see if it meets your requirements, here's a link to the package:

https://openwrt.org/docs/guide-user/hardware/bluetooth/usb.bluetooth

I flash my devices using a bash script (well ash), it just connects to the device(s) using ipv6, uploads the firmware and then ssh's into the device and execute the firmware upgrade. You could tweak my script a bit to make it handle multiple devices at once. I did about 40 of them today using my exiting script, one by one while I was eating lunch and watching the news.

My script is here:

The other option is to boot into u-boot and flash from USB.

@Chris-Morgan Since OpenWrt hasn't specified any release date for 21.x, I'm not sure this is a reasonable request of Onion as their release would obviously follow that of OpenWrt.

I can confirm that 21.02 RC3 does run on O2S+ but you need to manually configure the WiFi, same as 19.07. I've been running 21.x for 2 or 3 months on a POC custom board based on O2S+ and thus far no real issues. So far the only nagging concern is the WiFi connections seem to be a little slower than my 18.06 devices using Warp Core. Haven't had time to investigate in detail thus far so I may be wrong.

@Russell-Pirie Omega can run NodeJS, and there is an OLED expansion available so it's not difficult to build a POC. Omega doesn't have bluetooth however take a look at this project that explains how to use BLE on Omega devices:

https://docs.onion.io/omega2-project-book-vol1/bluetooth-audio-speaker.html

You probably don't need to boot from SD Card, my own Omega2S+ based devices use SD Card for data storage and SQLite3 database.

I think the main factor you will need to consider is if the Omega2S+ has sufficient computing power to meet your needs.

Omega devices run OpenWrt which is basically a cut down verison of Linux so porting is not typically a huge challenge. Configuration of items such as WiFi can be achieved using "UCI" and "UBUS" interfaces that you can intereact with using JSON, my own device configuration interface is based on PHP and utilises the CURL API to interact with UBUS and configure the WiFi, TimeZone etc. for user setup.

@Williamson Please tell me the mathematical answer to 28 div 14.

@Ioannis this thread may be of use to you:

The data sheet doesn't tell us a whole lot, have you contacted their support email address and asked them to provide further details?

@elPepino have you looked at the code for Omega Dash? The Dash uses a frame buffer to drive the screen and is based upon Omega2S+ and uses LVGL. I also wonder if you could use the Dash then use a USB LTE device
