@Gilles-BILLARD from the photos it seems you didn't connect a radio. If that is the case, the loop will not be entered and your arduino won't sleep!

Gilles BILLARD

@Yveaux
YESSSSSS !<
That was the last problèm to solve.
Back with my own MySensors routine all is perfect ! (8uA in sleep mode)
I am very happy now and I thank all those who assisted me.
You've made my day !
Gilles

skywatch

@Gilles-BILLARD @Yveaux beat me to it! - But I bet you are a very happy person after that - it is easy when you know how! :)

tssk

@Gilles-BILLARD Damn! Why did I order UNO if I could use another Pro Mini for programming... :)

Gilles BILLARD

@tssk My Pro-Mini's are 3.3V, so this way I avoid the resistors dividers wiring to change 5V (Uno) to 3.3 (Pro-Mini);
May be you love creating problems where there are none ;-)

Gilles BILLARD

Hy guys; So sorry but the procedure ran just once :-/
When I reproammed my soldred Pro-Minis (via the radio socket + 1 air wire to the reset pin) none was running as expected; The issue was a kind of permanent reboot..????
I tried to burn the MinCore bootloader and load my sketch into several brand new boards and the result was the same...
So I simplified and simplified again the sketches until this one:


/*This sketch is cycling wether you comment MY-DEBUG.....

I have included the Domoticz log in the 1st one and the serial monitor report for the 2nd.

You can see, if "delay(xxx)" is in use, all's Okay, but if "sleep(xxx) is employed, the sketch is cycling in both sketches....
What is happening?

Prog.setup

Yveaux

@Gilles-BILLARD what pro minis are you using? The 3v3 version only goes to 57600 baud, so 115200 is likely too much

Gilles BILLARD

@Yveaux Yes Yveaux, you're probably righ, but, if I use AVR bootloader and Test Nb 2 the serial monitor says:

One more point: Once the Pro-Minis are burnt with MiniCore library, I'm not able to revert on standard AVR bootloader; They are somehow bricked on MiniCore bootloader

Gilles BILLARD

@Gilles-BILLARD
Update: Today, using Arduino UNO as ISP (instead of a ProMini as ISP), I was able to "unbrick" one Pro-Mini and revert to standard AVR bootloader

skywatch

@Gilles-BILLARD Something is not right with either your set up (wiring etc), settings or installation of arduino IDE/libraries.

I just tested a 3V pro mini and was able to to back and forth freely between MiniCore and AVR bootloaders without issue. Two blinks for Minicore and one blink for AVR.

A USB programmer is usually cheaper than an uno, so why not try one and see. That is what I use and the only difference is less cabling and only one arduino in the mix.

In one photo you show nrf24 - are you using FOTA? Is this connected when bootloading the chip?

The error you described a week ago about optiboot should not happen and you should not need to change anything. Try reinstalling the MiniCore library again following the instructions to the letter. Have you in any way modified your boards.txt or changed your arduino ide from default settings or installation path in any way?

Gilles BILLARD

@skywatch When I try to use the red ISP (based on a FT232R ) you can see on the pictures I joined, I receive an error msg like :

avrdude done.  Thank you

That is the reason why I used or Po-Mini Or UNO as ISP.
I tried to change and test many others drivers for my FTDI (for 2 days) unsuccessfully

are you using FOTA? Is this connected when bootloading the chip? As you can see on one picture, in the programming section, NRF is NOT wired to the programmed Pro-Mini.
Neither it was when I tried to reprogram the wired Pro-mini because I was using the NRF socket to acces the Arduino pins.

.....or installation of arduino IDE/libraries I checked that as well and installed the new Adruino IDE 2.0.0 beta.... same problèms :-//

Gilles BILLARD

@skywatch said in 💬 Battery Powered Sensors:

....... Two blinks for Minicore and one blink for AVR.....>

Thay is not my case; 1 blink for AVR and NO BLINK for MiniCore !?!?!?

Gilles BILLARD

@Gilles-BILLARD Now it is OKay with that blinks; 1 for AVR boot and 2 for MiniCore and I can revert from one to the other and vice-versa.
( I removed all concerning MiniCore and reload it )
But sleep() is still giving the same issue

skywatch

@Gilles-BILLARD You remembered to connect the nrf before going to sleep?

Gilles BILLARD

skywatch: You remembered to connect the nrf before going to sleep?
@skywatch Yes, of course;
I'm 67, retired, and after 9 days (part time) on this issue, I give up !
I am therefore torn between crushing all that stuff between between a big hammer and my anvil or to discard everything to the trash can.
These sensors are useless if consuming 20mA H24-7/7 because they they should normally be used outside (in my greenhouses) powered by a battery 18650 + a solar cell.

Gilles BILLARD

Can anyone let me know if he sees something wrong in that log after a Min-Core bootloader burn in a Pro-Mini 3.3v
(I do not!)
I ask because it not the same file as the 1st one (the 1st was including the nb "115200" (bauds?) and now it is "38400" )

@Gilles-BILLARD I understnad your frustration - I have been there myself.

I suggest s simple node to test with, something like the door/window sensor with just one switch.

Take your promini, remove leds and power regulator (or cut tracks) then burn MiniCore bootloader with 9600 baud, 3.3V, 8MHz INTERNAL, BoD DISABLED.

Then add the radio module (you can try another if you have it - what radio modules are you using? - A link or photo might help, there are bad ones and fakes that could be a problem for you). Load your sketch and try again.

You can measure the current to the whole set up and then just the radio to see if radio is not sleeping. ....

I'll do that, but for my thermal sensor the test cannot be more simple

......burn MiniCore bootloader with 9600 baud, 3.3V, 8MHz INTERNAL, BoD DISABLED.

I don't have the choice for the baud rate; Where is it located ?

Then add the radio module (you can try another if you have it

I swaped everything I could. (The radio modules that was connected to the single functionning sensor included)

what radio modules are you using? - A link or photo might help, there are bad ones and fakes that could be a problem for you).

Bought from Aliexpress;

Load your sketch and try again.

I have done the whole process hundreds and hundreds of time

You can measure the current to the whole set up and then just the radio to see if radio is not sleeping. ....

Yes I'll do that...

@Gilles-BILLARD It's in the sketch when you start serial interface. As an aside have you checked the baud rate the pro mini or uno you are using as a programmer - maybe it is 115200 and that is optimistic for a 3.3V board. Make sure the programmer is using 19200 just to be safe.

For inof I am using arduino ide 1.8.13 and musensors 2.3.2 with a £2 aliexpress serial prgrammer and have only encountered warnings about sck (which can safely be ignored)....

That is not much help.
