I know them. Rf power is one thing. But i cannot believe, that a “high precise, long distance, low latency” LoRa based RC device can legally operate inside the duty cycles of 0,1% and 1%

Why a manufacturer of a Chinese fitness wristband / app needs access to my phones camera / contacts / mail / sms ect beats me…
I don’t work at a secret militairy location . my LAB is only a little bit secret 
Rather than using/polluting my phone I ended up synching to a spare iPad with no such data on it! 
Had mine for ~2.5 weeks now and am getting 6-7 days per charge ~inline with spec 
works well but reading in daylight a challenge and pain having to step forward in menu/options with no chance to go back if going one step too far…otherwise for ~£13 cant complain! 
agree 
Now what are you up to?

I’m using cheap ‘drone’ parts for a non-drone LoRaWAN POC… general nerdism
it’s for a wireless streaming video analyses with RPI that triggers a loramodule - experiment, waiting for receiver
I did a project earlier with a RPi and tensor flow, worked nicely. Trained it for traffic outside, it could see the difference between bikes, cars, trucks. How do you plan to feed the analogue video from the receiver to the pi for analysis? Is that possible?
I ordered this receiver and found online that it works on RPI… works as a webcam then, but wireless
there is a lot of this material , I’m not a drone pilot So I don’t know what’s good or bad…its a gamble

for the Tx side I ordered this video pal camera + 5.8 transmitter
Ah a receiver with usb out. Interesting! That could work indeed.
Soldering the SMD components of the shield for the IoT class node with a cooker. Never before I have soldered SMD so nicely.

brilliant… and now, how to implement that with ‘leftover’ wires pieces

huh… just playing a bit and testing if the TTIG is back online.
with a setup taped to my PC with a 3dbi antenna indoors
So I transmit a 3 byte payload at 20 db SF12 and got metadata from nine gateways back.
One 43 km away… is there something in the air tonight ?
I’ve 'seen :
Croeselaan - Utrecht
Betaplein - Leiden
Eschertoren - Leiden
all from Zwijndrecht (near Rotterdam)
- checked today after a coffee , seems I’ve forgot to set the power output, So maybe that’s why
Hummm - 23db(m) EIRP? major breach of EU regs!..who do I report you to?!

Next batch of 5205’s just arrived…mix of SMA & iPX, along with samples of the new housings for test - with & without Solar panel…competition for the ‘Nut’ tins!
Along with 2 more RAK Fibre Glass Antenna’s for upgrading a couple of the TTN deployed gateways from indoor to outdoor use to improve coverage & range 
I’m curious what your impression is of that new RAK outdoor gateway Jeff 
and who are your clients… what are their use cases,can you elaborate a bit
* I just realise… maybe all these sensors and gateways are for your own house and garden
Didn’t their fibre glass antenna get terrible results when tested?
