@bjornhallberg

while measuring current draw , was there FDTI adapter connected also?

@alexsh1
I was trying the same code on bare RFM69 board without any external libs,
just mysesnsors2.0 and 2.2 and 2.3 old drivers. 2.0 need 30ms waits 2.2-2.3 - up to 100ms for stable ACK's and sends

@scalz
NRF24 works fine without waits.... may be you know some direction where to dig in RFM driver for gold?

@mickecarlsson said in Very strange bugs. 2.3. RFM69.:

Note that the begin() function needs a mode parameter, and that is used in configure

Should be this one lightMeter.begin(BH1750::ONE_TIME_LOW_RES_MODE); but Koresh was asking radio related question...

ESUN flex filament used.

@kenci

EUR 18 the board with SI7021 and BH1750. extra 1EUR for enclosure if someone need it.

@kenci

Yes, in a week or so. Even with plastic enclosure ))

selected it will go out of range during node boot and cut the circuit making measurement impossible

my cheap one survives 20mA surge (RFM69 CW version) of initial communications and displays good reading afterwards. if you burned fuse inside, try replacing it temporarily with some thin wire for this uA tests.

multimeter

You should be fine even with a cheap multi-meter as long as it has uA scale.

should be around 7-10 uA and if you do not send JDEC to sleep it is 17 -19 uA.

to send JDEC to sleep\wakeup I use
_flash.wakeup();
_flash.sleep();

light sensor should be sent to sleep explicitly also.

uh... apparently, yes. dual dip cr2032 is hard to find item on ali.

Re: Button size radionode with sensors swarm extension

2 cr2032 winter upgrade - works nice

Keep working at -20 Celsius in a fridge. voltage dropped from 6 Volts to 5V and keeps pretty stable while sending temperature reading every 2 minutes for 2 days now.
