Re: Worked examples HTTP via serial port

Hi

You need to be a bit more specific in your requirement.

Android, Linux and Windows already have serial programs that can do such.

What is it you actually want it to do?

Re: SR04 Ultrasonic Sensor

Hi Lab is in a bit of a state just now, in the process of a good clean out, getting rid of the "might come in handy" pile amongst a LOT of acquired useless junk. That's my "Ivory Tower" up in the clouds, i.e. the mezzanine floor I built to elevate my status :) Scopes / analysers / soldering / test e...

Re: DSP made easy

Hi Whenever I could squeeze in the time I've been working my way through the tutorials and decided I needed a "white noise" generator so that I can experiment with filters a bit better. Six weeks later I'm in possession of a Chinese generator. Now I knew it was a kit but must admit to being surprise...

Re: IOT_Made_Easy - or not?

Hi

Admittedly I'm not that up to speed with this, but couldn't you use one of those generic 32's that have onboard charging? Power via USB and if "mains" fails, battery takes over?

Re: IOT_Made_Easy - or not?

Hi

The Raven has indeed disappeared but a Black Swan has taken it's place. Best not to leave that unattended.

Although both good, not as nice as Puffin (5000 years in the making, or something like that).

I have a few more bird related beers to get through...:)

Re: IOT_Made_Easy - or not?

Hi Work not holiday and I didn't know about the pencil museum. 2B or not 2B I guess? Fueled by Raven Red I discovered if I add in the IME component before I add in the Network Comms component, then no matter how many times I try the NC is a no show.

Re: IOT_Made_Easy - or not?

Hi I've been down South (or up North depending on viewpoint) for a few days this week in the Lake District. I've not been there since childhood and I'd forgotten how beautiful it is. Day trips, so long days and I'm just heading off there again today. No hardship with the scenery I pass through :) As...

Re: IOT_Made_Easy - or not?

Hi

Sorry, a little busy this week and I've not had time to post my TS mqtt file. If using the "free" version of TS then you are limited to how many posts you can make and also frequency too. I could only reliably post every 12 - 15 seconds or so.
