nRF5 action!

This is strange: now when I do the timed sleep on the infor-link module, it shows a current drain of about 60ua, whereas yesterday it was around 6ua. Maybe I somehow damaged it by connecting a couple of the input pins (A2 and A4) to Vcc? I wouldn't think so, though, because the datasheet says it should be safe to Vcc + 0.3v.
I have one unused infor-link module left. I'll try wiring it up, but without the input pins this time, and measure it. I'm wondering now whether the sleep current will measure out to be 60ua, or 6ua.

Is there a mysensors demo sketch that involves i2c? I could try it on my end, though I expect I'd probably get the same as you.@NeverDie said in nRF5 Bluetooth action!:

I have used I2C with an display and u8g2 without any problem.

With the nRF51 there is an bug, after using the debug interface the current consumption is higher until reset.

The answer is.... neither. This time, with a fresh infor-link module, it measured at about 16ua.
However, I'm guessing there's quite a lot of noise involved, because this time I noticed I could change the reading just by moving my hand closer or further away from the infor-link module. So, I may have to scope this to see what's going on.

Yes But it seems to have trouble reading sensors.

So, I decided to try running it from a 10F 2.7v supercap and see how long it lasts. It reports its voltage once every 5 minutes. I'm using Domoticz to log the values and graph them.

Does it rest entirely on Sandeep's shoulders as to if/when it gets fixed? I'm trying to understand how big/small the workforce is.

@d00616
No not mine but that is the issue i was talking about.
When connecting DS3231 RTC i get the same as that guy mentions.
When connecting HTU21D the readings are all over the place.@rmtucker said in nRF5 Bluetooth action!:

Trouble is the aeos is using nrf52 not nrf51.At least it would be something, rather than nothing. Wouldn't you rather be on nRF52 anyway? It has advantages. (I say that even though I do have some nRF51's on order, but only just because they're small and cheap).

@NeverDie
yes but it would take 4-6weeks and i was impatient so thought i would start with what i could get.
But it seems it does not work on either looking at some of the other issues on sandeeps github.@rmtucker
Hmmmm... Maybe this explains why I didn't notice any MySensor's example demo code that used I2C.On the other hand, I wouldn't think the gap can be all that big if d00616 is able to use I2C for display purposes.
Still, that by itself doesn't get you there.

On the 10F supercap, the infor-link module was losing about 0.025v per hour, and that included it reporting its voltage every 5 minutes. So, I've hooked it up to a mini solar panel now so that the supercap will charge during daytime, and with that it should run in perpetuity. :)

@NeverDie nice results! What kind of overcharge protection are you using?
A 2.7v LDO. Very low quiescent current of just 1ua.
