Are you a mobile or desktop app developer?

@zapta I unfortunately didn't have the time to build your stepper analyzer, but I appreciate your development with great respect. You motivated me to start with PCB solutions on my own.
Building the DWC, I want to design it with adapters, so different solutions can be connected. I'll tell you when I have the time to start.
-
@chrishamm do you have preferences which libraries to use for future DWC development? E. g. this plugin can be implemented with chartjs or babylonjs. BabylonJS is fast, which may be more important for this plugin than a nice coordinate labeling, but has a not so well manageable coordinate system.
-
@joergs5, @chrishamm, looking at the link below, it says that the web ble API, which is required to connect with the ble device, is "HTTPS only". What does it mean for potential integration with DWC?
-
@zapta looking into DWC, it consumes some https sources like configtool and REST connections, but let's see what chrishamm says.
-
@zapta I searched the web a bit, there are multiple library projects to read NRF52 like https://github.com/NordicSemiconductor/pc-ble-driver-js https://www.nordicsemi.com/Products/Development-software/nrf-connect-sdk https://www.novelbits.io/smart-ble-lightbulb-application-nrf52/
so I expect we find a library which doesn't have the https restriction, in case it's a problem. DWC itself is unprotected, so there is no additional security to protect the bluetooth data. Taking over the printer is a higher risk.
About making DWC https capable if desirable, there was a thread here: https://forum.duet3d.com/topic/13851/dwc-https-and-password-protection
The Web Bluetooth lib links to this page: https://w3c.github.io/webappsec-secure-contexts/#intro where there are examples mixing http with https (e.g. 1.1 example 4), this may be an option.
-
@joergs5 I'll upgrade ChartJS to v3 in DWC v3.5 and likewise the BabylonJS dependency because the heightmap + Gcode viewers depend on it (fortunately we're no longer using ThreeJS). So it's up to you which one you want to use.
DWC can operate in HTTPS mode but only if an SBC is attached and if HTTPS is enabled via
M586 P0 T1 S1. -
@chrishamm thank you for clarifiying.
-
@zapta dear zapta, are you still interested in a DWC plugin for this motor analyzer? I can begin developing it next week (slowly). Whether I can manage to use bluetooth without https or how to find a workaround, I am unsure and have to check.
-
@JoergS5, yes, very much so. Either DWC or any other cross OS client.
BTW, did you try the python client?

@zapta thanks for confirmation, then I'll start this week. I didn't look at the analyzer and Python yet, but I will use Python as a starting point. I want to use DWC, so it is integrated into the other Duet related tools.
Can you please give me a proposal where it should be placed in DWC. Please plan for displaying data of multiple analyzers. I need this proposal not now, but the next few weeks. I expect it would be valuable in some situations to show it together with other information in DWC, so showing it together with this information would be good. But I don't have an overview over the use cases.
