It's really thick. Would be nice if it was smaller. Product page doesn't mention Wifi or Bluetooth. Dunno what's the usecase of a watch with GPS and Lora, but no Wifi and Bluetooth. I think Wifi or Bluetooth would be nicer instead of GPS and Lora. If the screen is monochrome, it looks awesome.
I ordered 2 T-Impulse, want them to trade GPS data, no hurry but it would really be nice to have a fresh tutorial explaining how to accomplish that soon after I get them from China. Your explanations for dealing with things electronic from China are the best on the internet. Nothing seems "plug and play", there always seem to be some easily overlooked detail that causes much frustration. Thank you for your tutorials.
Good video idea! I have two of these myself. I'm going to have to say Arduino IDE is the way to go. This is the sketch I'm looking at. github.com/Xinyuan-LilyGO/LilyGo-T-Impulse/tree/master/Example/ArduinoDemo/T-Wristband-S76G Now the head scratcher is, you have to define the LoRa as sender or receiver. I have to ponder how to make each send and receive. Look it over. Happy to hear your thoughts.
The Meshtastic site doesn't list this as compatible. The github site for the device: github.com/Xinyuan-LilyGO/T-Impulse Only includes SoftRF, not Meshtastic. Best wishes.
Im completely new to LoRa, Programming and Radios, but im trying to make with the watch a simple backtracking hiking watch. So you hit a button at the start of hike, and itll constantly give you dead reckoning back to start point. I have no idea how I will accomplish this but it is my project currently. (among like 30 other things)
Best advice, map out the program in plain English then master each step in code, one step at a time. If you can say what the program should do and what you say makes sense, you can program it.
I recently received 2 of the Lilygo T-impulse wrist bands. They do communicate reasonably well, transmitting or receiving LORA packages. I am disappointed in the gps performance. One did finally get a fix (if the number indicates the number of satellites-it got up to 12-13). The mosquitoes are terrible so gave up waiting for the other band to get a fix. The lat and long only displayed to 3 digits, not enough for determining an accurate location. That might be a software issue, will try to address that. The display was extremely difficult to read, impossible in sunlight and difficult in the shade. I do look forward to seeing what they are capable of because the LORA seemed to work reasonably well though I didn't go far from the house because of the mosquitoes! I am hoping that I will be able to program them to alternate sending and receiving GPS locations, shouldn't be too difficult once I figure out how to reprogram them. Would be handy for keeping track of each other's location at the state fair for instance. Maybe displaying distance and bearing to the other wrist band.
Can these run Meshtastic? Use case example: - Each vehicle has a mobile Meshtastic node in it - While at school, work, shopping, etc. the car node is too far away for Bluetooth to connect to it - A wearable Meshtastic node will receive Bluetooth from the app, then use LoRa/Meshtastic to relay to the car node (or other node), so you're always connected, even when your "node" is further away than Bluetooth with reach. Thoughts?
Oh that's interesting. I haven't had any experience with LoRa; I had assumed that the frequency band was a matter of which LoRa radio chip was being used. Is that not the case? Is it simply something one can set in firmware? That implies, in turn, that the current status of the 915MHz T-Impulse as being 'Out-of-Stock' basically everywhere should not be a tremendous impediment to getting started...
Yes, 433, 868 and 915Mhz frequencies are specific to the chip. If you are in the U.S for example, you need the 915Mhz model. You can't program a 433 or 868 model to do 915Mhz. I hope that answers your question. Happy New Year.
@@ShotokuTech Yep! Thanks so much for setting me straight. I hope Lilygo intends to produce more 915MHz T-Impulse; they seem to be sold out everywhere.
Will this device be like a full TTGO on your wrist with Bluetooth connection to android and IOS smart phones for using the send and receive functions for texting, etc. like we have seen in other videos?
I haven't really considered it. But now that you ask, I had to look. It has a microphone, amplifier, acceleration sensor and LoRa! $41 U.S.! I might get one soon.
it really sucks that the display is not covering more of the watch's display surface, really a missed opportunity. if something is restricted to mostly text it should at least make the most of if!
I bought this device to use it as a tracker for my bike, in case of theft. but I cannot find the way to properly set it up? has anyone fully set up this device for such purpose?
I work in the firearm safety space a lot. In Australia, they have a lot of open space people can hunt, and they have hunters who enter from different areas and thus are not aware of others who may be within 1000 or less yards of each other. An interesting use for this would be for them to be required to wear the bands while on the property hunting. If the bands which would be beaconing their own position and listening for others, were to become aware of another band within say 800 yards, the bands would notify the wearing of the proximity of the other hunter. The band has the GPS, compass and Lora, all you need for that application in a simple package with battery at a not out of this world cost. Pretty good stuff. Thank you for highlighting this very cool product.
That sounds very much like "sending APRS-like messages over LoRa" and even without a firm regulatory requirement for its use, getting enough people to adopt that kind of safety measure seems as though it might save many lives.
hi, just received a pair of those wrist bands, however neither of them are recognized in Windows 10\11 device manager , there is no "stm32 bootloader" in the devices manager, any idea of how ti fix that? it seems to a hardware issue, thanks
I imagine a gifted coder could do so if they want. I do see some hints in a quick search of "Lilygo TTGO LoRa TTN". Some of their products do seem capable of doing so. So there will be some Lilygo library support. Wish I could help more. I'm sort of jaded towards TTN. I have the official The Things Indoor Gateway. They really do not make it clear how to onboard this gadget until you have already joined it to TTN. Then it clearly states do not onboard your TTN the way you just did. At this point the GUID on the label is useless and you need to do some shell command gyrations to undo what you did. I spent some time trying to run this in both Windows and Linux with no success. I basically have an $80 brick. I'm not super motivated about TTN. LOL. Thanks.
@@ShotokuTech I have several devices working in TTN of the RAK and DRAGINO marks but not in LILYGO. I want use LILYGO TTGO T-IMPULSE WRISTBAND for conect to TTN and work in the similar mode that the other my devices...
868Mhz version can be configured to do 915Mhz. I need to get back to this device and see if I can actually program it. Tricky device driver stuff you have to do.
I am trying to program GPStest example, but I can't upload it. Is there anyone knowing how to program using arduino? My PC recognize it as "NUCLEO_L073RZ CDC in FS Mode". I reinstalled the driver with ZADIG, but still same. I don't see STM32 BOOLOADER. Arduino does not recognize the device.(no com port)
@@andrewtitcombe8378 I did just get it to detect. It took a bit of wrangling. I had to make sure the watch band was not interfering with the USB C cable. I had the watch on its side and pressed the cable in firmly. Finally got the USB song to play. Then I pressed RST and BOOT. Released RST, released BOOT. It recognized as some device that no driver was found for it. I pressed RST again and it said STM32 on COM6. I had to press that cable really firmly. Sorta disillusioned by this.
@@ShotokuTech Brilliant fast response . Followed your instruction . got the USB song. Updated the STM32 driver. Did the button press sequence and now recognised in arduino on com 15. Without your help there was no way i would have pushed that USB on as hard as that. Going to leave it plugged on,.While prototyping my code.As i don't think those UBS tracks on the board will take much to wear out or break . With repeated unplugging.
make this watch deep sleep. and wait for receive rx signal a specific code every few minutes. once it receives code, means a node is nearby example lora attached on a drone flying @ 1000mtrs AGL make the device wake up, activate its gps and send a burst of ID, location data then go back to deep sleep again and wait for the packet code for long endurance tracking and track only on demand. Good as a tracker.

This is very cool, I'm in love with LORA... thanks for these videos one day I will feel confident enough to dive in deep on hardware
I love LoRa too! Still haven't gotten my head around LoRaWAN though. Thanks.
Cool. I think Unexpected Maker is releasing an esp32 watch as well.

Do you get the "new device" gong from Windows? If not, push the C cable harder into the watch.
