@scalz said in HALO : ESP32 multi transport GW/Bridge for Mysensors: the webapp was great, but I converted it to native crossplatform app for better versatility&perf, so I can use one app for my devices, like Ethernet for HALO etc, or Serial for my other Janus gw dongle, bluetooth.. To be honest, I've not updated anything yet for a few reasons, like very little spare time for a public release + support for such "big" project. (easier to handle local projects). Sorry, still no eta for the moment.. It is clear that there is not enough time. But this project can become popular. That's what's missing MySensors. ...This void must be filled.

Qu3Uk, I did get a chance to test with a Fitbit recently. It technically worked, but not all that well. The thing is, the Fitbit only advertises every 2 seconds so latency is a bit high. But worse, its apps really want to be connected to it often to sync; and whenever it's connected, it stops advertising and the detector then can't pick it up. TommySharp, At this point I don't plan to modify the board much but having it read environmental sensors would be a cool feature! For that, would be nice to make little beacons that read sensors and advertise/broadcast the readings every few seconds. Then they could be very low-power, run on coin-cells for months, and could be placed anywhere instead of needing it to be hooked up to USB power like the main board is. Like these: https://sen.se/peanuts/ I'm curious if it could read them. As for enclosures, I know. I would love to have some nice ones but at this point I'm making too many boards to 3D print enclosures, but too few to afford injection-molding tooling to make a custom case.

@victus Im not familiar with this components you mention, you need to test yourself, cant help you with the technical stuff. It does not seem to be a fully functional ECG but a heart rate monitor. As epierre said above, you need to define if you want to monitor or have a fully functional ECG, its a big difference. With a monitor all you get is pretty much your heartrate and you can detect arytmias. A fully working ECG is normally made with 12 leads and is used to in detail know how the electrical depolarisation from different time and direction/place within the heart muscle works. Holter is a example of a heart rate monitor over time.

@terxw okey, thanks for reporting back !! Let me know if there is something else. This is a 0.5v so I'm open for improvements.

Hi @Siddharth-Velappan The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time. Do you mind explaining your setup a bit more? I would love to do something similar but I do not know where to get started with the PIC microcontroller!
