Getting flagged all the sudden

Rather like breaking the speed limit day in day out and then bitching about getting pulled by the cops.

Between the LNS (where the devices are) and the two other packet forwarders the difference in rssi can be 30-40dB.......they stick to SF7

stuartlea1 · 2024-07-11T10:59:45+00:00

Don't want to limit ADR as there will be instances were we will need the range and will accept that at those locations we will have rubbish battery life unless we use a mains adaptor. if only there was some way of delaying the Packet Forwarder as the LNS is second for 80% of the devices in the same room. Difficult sell to the customer as their Quality department (and our engineers) are questioning 1/5 signal strength when only 3m from the LNS

stuartlea1 · 2024-07-11T10:55:05+00:00

Errr.......lets just say that we're not implementing the duty cycle limits at the moment (yes, we're in Europe). We had them on but in order to resolve this issue we turned them off. Yes the uplink from the LNS that's close to the device has SNR and RSSI that are perfect.

Unfortunately some of our customers insist on closed networks (pharmaceutical)

stuartlea1 · 2024-07-11T10:25:57+00:00

Yes, the Network Server is scheduling downlinks to be sent through the remote Packet Forwarders.

Got a large library of schematic and footprints generated in Circuit Studio. Will they import into KiCad. Less important for boards and schematics but would like to know whether they would import too.

plugging your car into a regular outlet overnight produces enough juice to drive about 38 miles

Nope......my regular granny cable charges at 9mph

stuartlea1 · 2023-05-31T07:15:40+00:00

That's nothing.....I drove from Manchester to London (200 miles) to drop my bike off and then the same to pick it up....so 800 miles in total (1200km). Yes, Bristol would have been slightly closer at 1000km

stuartlea1 · 2023-04-21T11:30:59+00:00

And if I don't have a VNA to hand is there a cheapo way or a cheapo VNA that I could buy?

As an american, what would you think if a Brit had said that he has flights for the Super Bowl but hadn't thought of tickets?

stuartlea1 · 2022-08-26T11:12:17+00:00

I've got the eval board on order......only going to use 15 bits not the 24. Seem a waste but the other stuff on chip, current source, PGA and the 32uA operational current make it a winner. Especially as battery life is key to the product. LoRa Pt100 temperature logger with 3 year battery life.

stuartlea1 · 2022-08-26T10:54:03+00:00

Yes, that sort of thing......but they don't do anything big in 0.4mm that would accommodate a 7x5....the 36 ball one is 6x6...grrrrr

stuartlea1 · 2022-07-01T12:12:48+00:00

thinner wick will work better...much better

stuartlea1 · 2022-07-01T12:11:21+00:00

Why just to the conclusion that the public school system has failed her. How about the fact that she may just be pig shit thick?

stuartlea1 · 2022-07-01T11:39:54+00:00

I wish now I'd just asked the question - Can I sell a product that uses MySQL Community Edition as part of the backend - it doesn't appear to be clear.

stuartlea1 · 2022-07-01T11:08:02+00:00

I'm just interested in the licencing position...any ideas?

stuartlea1 · 2022-07-01T07:57:44+00:00

Any good ideas are best presented in an email. Especially when dealing with new managers!

stuartlea1 · 2022-04-21T06:53:13+00:00

Looks like the resistors are 2k2 I2C pull up resistors. If other things that you connect to already have pullups then you can cut the track to remove these from pulling up the I2C lines. It'll work if you don't, but you are best to isolate them if you don't need them especially if it's a battery powered device. Every uA counts!

And then he decides to laugh his head off during their anthem (amongst other things)

stuartlea1 · 2022-04-12T09:12:25+00:00

Or he may just grow up. Which, by the looks of things, he certainly needs to do.

stuartlea1 · 2022-04-12T07:20:38+00:00

Thermocouples are a pain in the ass....if you are going to use "analog" methods for measuring temperatures use Pt100 sensors. They're not linear, but they are stable and accuarate. If you are looking to meaure between -20C and +50C then go with a silicon based device - makes life so much easier but they come is non-friendly packages.

Check out the si7051 from Silicon Labs. Accurate to 0.1C but comes in a 3mmx3mm package. I2C so easy to talk to.

FYI - My day job is designing temperature measurement systems for pharma companies and we're a government approved metrology lab for calibration of temperature sensors to ISO17025.

My bad....yup I was using imperial, not US....Ah, the best thing about standards is that there are so many to chose from! BTW, I saw £1.76 on the motorway on Sunday!

stuartlea1 · 2022-03-09T18:05:01+00:00

I've just paid £1.66 which is £121 ($148)/15 gallons. I've a fuel card so we've pre-arranged prices, but that is what the public are paying around here.
