Tell me about it. I'm still trying to deal with the various .yaml files on Home Assistant / ESP32. ;-(
<snip>.Hehe. Doh!
I remember the GEC / Marconi PCB's being quite nice (along with STC) on the BT PCM / TDM kit I was bench repairing for BT in those days. It was made for BT by several manufacturers, the worst being Plessy because they used SRBP PCBs and with any modules that carried anything heavy (Txfmrs / filters), the PCBs would often end up broken / cracked. Remove the component(s), cut a Paxoline 'patch' to strengthen the broken area, mark the outline on the PCB, abrade the area and the back of patch., apply two part epoxy and glue patch on board. Later, re drill component holes and re-fit / solder the components and repair any broken tracks with BTC. Too many Plessy boards in your batch would slow the batch but I was told by the union to 'slow down' as all this stuff had agreed times and I was mucking it up. ;-(
So, given I couldn't work 'slower' I sneaked in several private projects. I still have one here, a 'heating' indicator LED on my (BT, fell into my bag when I left) Weller soldering station that was a small rectified PSU (off the 24V AC transformer) that drove a led on when the output voltage was depressed. It did a few things, it told you when it was 'ready' from turn on (not really an issue at work as it was on all day), it gave you an idea if it was still coping when heating heavier joints and if the Curie tip / switch was still working.
Yeah, I think once they had some gear working it was generally 'good'. Visions of some very knowledgeable / Old Skool design Engineers in there somewhere.
Nope, a pretty straightforward Enc / Ack protocol?
Sounds a bit like a broken CSMA/CD? ;-)
Gawd.
I was there a few times with Modem manufacturers and their interpretations of the CCITT 'Red books' (I think it was at the time) 'recommendations'. ;-(
Yeah, that was something a mate had to come to terms with when he moved out there from AWE Aldermaston.
Yup. When he came back for a visit and was a passenger with me in the car ... and I stopped at some amber lights he looked frightened. Apparently, in Italy (esp the South?) you *never* stopped on the amber and so he was bracing for someone to hit us in the rear!
That sounds like running MQTT over a Zigbee HA link as it's supposed to provide a stronger level of ETE comms but I really haven't worked out yet how / when / why it comes in? ;-(
