The metal antenna on the side is the GPS antenna, not the LoRa antenna. The LoRa antenna is built into the PCB itself as a trace. This is probably similar to the Nano G2, which was designed specifically to get good reception while in your pocket and next to your body.
Hi Andy, which version of the Lilygo T Deck Plus fancy ui are you using? When I try and detect signal strengths like you are doing in this video, it either won’t show all of the active nodes, freezes, crashes, or all three! Thank you for your help in advance mate. I got into Meshtastic because of your fantastic videos 😊
Andy, I don't know whether it's just the warm weather or something else having changed, but I'm now picking you up most days from Northamptonshire. I can see you on the node list & the public channel, but I don't think you are seeing my replies or messages (MIK3). Anyway, great stuff...
Oddly high SNR readings a couple of times there (incidentally higher positive SNR is better, but 60 has to be misreporting). I've been ignoring RSSI mostly on LoRa since i discovered the SNR is most important for reliable communication as LoRa can decode below the noise floor. LongFast works reliably down to about -17.5 SNR if I'm not mistaken.
There was an issue with the SNR calculation for the LR1110 in the underlying radio library Meshtastic is using. It's fixed, but we're still waiting for a new release of that library.
Do you have a NanoVNA yet? Would be nice to see exactly how resonant the cheap (read: not TBS Diamond) antennas are at the frequency you're using. If you don't I'll lend you mine no problem.
SNR is signal to noise ration. RSSI stands for received signal strength indicator. RSSI is most often a negative number. For LoRa you could say -40 (dBm) is good/strong signal and -120 (dBm) is pretty weak. It's a logarithmic scale and 10 (dBm) difference means 10x weaker or stronger. So -100 (dBm) is 10x weaker than -90 (dBm).
Andy, can this T1000 be flashed on the Meshtastic website or do they ship with meshtastic already installed? Does this T1000 work at 868mhz? Regards, you are doing a great job!
After a rough look, the peak value of sending messages is approximately between 150mA-160mA. When GPS is not turned on, the base current is between 20-25mA. When turned on, it is between 25-30mA. If GNSS is normally on, and the battery life is about 2 days .When the GNSS sampling period is greater than 1 minute, the battery life of 700mA is about 3 days
Hmmm, your vid shows that the t1000 was consistently better on snr with level around +5 than even your big antenna on the t-deck but you only talk about the rssi, afterwards you mention that snr if the think to watch for. Doesn't make much sense
How did you get access to the GUI firmware? I'd love to test it out but I'm struggling to find the repo/any info on getting a copy. That t1000e is great, I could see a device like that making meshtastic much more approachable. Stick that in one of the card slots on a wallet-style phone case and enable meshtastic connectivity? yes please!
It's called Fancy T-Deck and getting it off Github and onto my T-Deck has been the bane of my existence this week! It's been taken down for the most part but versions are out there. It's in it's infancy and will no doubt improve but honestly I'm guessing the T-Deck is hardware limiting for it. The T-Deck Plus though comes with it, I think.
"British Wilderness" LMAO 🤣
Andy 😆🍻
Seeed Studios always make quality gear 👍

yeah, looking forward to seeing the coverage comparison between the Nano G2 Ultra and the T-1000e😀
Always like your energy Andy. 💚🍻
Excellent review Andy! Hoping to get my hands on some of the t1000 e cards soon!

Nice review. I've been eying those little cards as trackers. I hope the 915MHz version is tuned just as well.

@@GUVWAF good to know, first time I've seen it do that.
Nice test Andy !
Totally off topic but I was just thinking about talking to you about Rebirth RB338. Loving the vids BTW good work fella
Making it really simple makes it so much more fun. I haven't recorded anything for years.
Would be interesting to see if any of these inexpensive Chinese HTs could have a go at this type of thing
Looking forward to getting my seeeeeed
I think RSSI is a log scale, so -90 and -95dBm is ~3.16 times greater signal lower.
Yes! This comment should be higher up.
Think we need to send you a RAK Blade to test Andy!
Yeah do it! 😁
I would love to see the T1000e with the new litephone 3 which is the same size and use the eink screen

Interesting video, but not knowing anything about radio I did not understand any of it. SNR? RSSI? No idea.

Yeah you can flash it using the web flasher and yes it supports from 863-928mhz bands. Thanks!
Did you preorder a T-Deck Plus from LilyGo? I ordered one of these Sensecap also.
Yeah there's one on the way 👍🏻
what's the battery life from this card ?

@@dylanazure2298 thanks u sir,that's really helpful.its not really a long battery life but it's perfect for the Wife ;)

well i guess ill just sit back and find out i guess lol thanks for sharing
lol i dont even know what im looking at what does it do and why
