@rozpruwacz o really, yeah me I guess .
I'm on my phone atm, but a similar sketch should be in my openhardware.io projects. (Have been playing around with it, but those where minor changes)

@rozpruwacz seems about what I get aswell. I get 18 /19 uA on my boars with a si7021 and am612 PIR sensor.

However, I have not yet looked at lowering this for instance with dc/dc mode.

Also I don't know what and how a wdt (really don't have a clue how to use it) would work and impact the consumption.

But all things considered, my nodes are powered with 3 AAA batteries, that would take it past 5 years.

@spanners to give you some assurance about these modules, I programmed 15 units by now, eventually all were working at the end.

Upload looks fine indeed,

I'm not sure if they hang, I just think the pinout wasn't right.

Whenever Pins are not working correctly I check the files again (to be sure), then close down the Arduino IDE. And open the sketch you want to upload. somehow it looks like the pinout isn't coming through correctly when a different version is also opened.

@berkseo great, I'm going to try it soon, I have 5 nrf52832 chips laying around (got them with the nrf52832-DK). Would be a shame if I didn't use them

Great work, this looks interesting.

How did you solder the nrf5? Can you also put in a schematic in PDF?

tonight, I let a node send data to the gateway, this one hangs after a couple of hours, but this time, I also hooked up an FTDI to the node, to have some readout as well from it.

It also broke down at the same stage like all the others did:

45381108 TSF:MSG:SEND,215-215-0-0,s=1,c=1,t=0,pt=7,l=5,sg=1,ft=0,st=OK:13.3
45381165 NRF5:SND:TO=0,LEN=32,PID=1,NOACK=0

Why would it always hang on that this same line?

-- while operation, the node stays at a solid 3,0 V during all operations.

@electrik,

ill take a look at it, yup, a 100nf and 100uf next to the nrf52832. One setup had a 470uf for good measure..

@electrik

It an assumption but I guess so, its an ST-Link V2 as power for the Ebyte module.
I use it to test my nodes with. So far none broke down.

The Weemos has its own USB power

I've been troubleshooting for the last couple of days now;

so far:

• switches Weemos modules => both crashed
• switches Ebyte modules => both crashed
• powered the Ebyte modules separately from the ESP8266 => no luck eighter

2 things that came up "positive"

• remove: #define MY_SECURITY_SIMPLE_PASSWD => it ran all night without any errors
• FTDI + nrf52832 (serial gateway) + #define MY_SECURITY_SIMPLE_PASSWD => ran for the last couple of hours without any incident.

I don't know if it makes any sense, but when I combine the weemos with a nrf52832 (using Serial Gateway) is get bumps in the road. separate they work like charm.
