Can't get the esp stable

#1 Post by DMeekelenkamp » 16 Dec 2015, 08:47

Hello,

I have a problem with all my esp units (4 pcs)
I run them with R48 and core 2.0.0

When I run the esp's without a sensor for example ds18b20 they run fine without problems.
But when I connect a ds18b20 after a few hours the esp is unreachable and I have to disconnect power and then it is up again. I thought it was my power supply....

What I did was Esp01 with dallas and Esp02 without dallas on de same 3Amp power supply and this morning the Esp02 was still up and running and the Esp01 was unreachable. I also did a log on the power supply and there where no dips.

I also have nodemcu v0.9 with this one I have the same issue. Stable without dallas with dallas it is unreachable after a while.

If it's unreachable, it could have rebooted into upload mode. I've seen this behavior in the past but not recently on my units.
I'm using NodeMCU 1.0 boards and always connect Dallas and DHT to GPIO-12 and/or GPIO-13 to stay away from GPIO-0.

What GPIO are u using for the dallas sensor?

I used gpio16 for the dallas

I will try gpio12 to see if it makes a difference.

It doesn't make difference if I use gpio12 Esp01 is again unreachable. Also Esp02 without sensors is not reachable. If I disconnect power and power up again there are back online.

There also not in ap mode. Maybe in Boot will it help if I pull gpio0 high?

Esp01 was online for 5 hours
Esp02 was online for 13 hours

I don't have domoticz running all the time because I use it now on my pc. Does that something to do with it?

did you try with domoticz, i think maybe can be this, my advice are to put you definition of domoticz on espeasy.

Had that sort of problems too with my ESP modules.
I placed a small capacitor (1-10 nF) as close as possible to the reset pin and ground to prevent the ESP from resetting on EM interference.
I also use an extra capacitor (1-10 uF) between Vcc & ground close to the ESP Vcc pin.
That made them stable enough too.
You can also have a bad breadboard which causes problems, or perhaps bad dupont wire/connector.

I had the same problem with v48 and v51
latest version 52 fixed the issue (do a reset as well configure it from scratch just in case).
and I 2nd the 10µF capacitor close to the VCC and GND on the ESP to smooth the power

Uploaded r52 2 esp's remain stable now for 17 hrs without any sensor attached.

2 esp's only have a ds18b20 and they don't run stable.

Both give same error. If I disconnect the ds18b20 than there is no problem. I also cannot Boot with the ds18b20 attached. Maybe a bug this didn't happen with R48

Hello,

Can somebody please tell me there exact setup of theRe esp and how it is running stable?

My setup:

Esp-12e loaded with R052 core 2.0.0
Flashed as nodemcu v1.0 4m (1m spffs)

Power supply 12v 2A 220v ac to dc
Buck converter 12v to 3.3v capable for 3Amp
Image

Extra capacitor over 12v side 10uF
And over 3.3v side 10uF.

Only sensor attached ds18b20 on gpio 13. +3.3v signal gnd. between 3.3v and signal 4.7k ohm resistor

And every morning I check the esp there is no connection possible. I really don't have a clue what's going wrong here.

If possible in your situation, hook up the unit to the serial port on your computer, set serial debug level to 4 and keep the serial monitor running for a day. Then you may get a clue about what's going on there.

Some possible causes:
- It boots into upload mode and that's the last thing you will see in serial monitor: boot mode:(1,6) or boot mode:(1,7)

- It looses WiFi connection and can't reestablish. You will likely see some messages from the SDK core routines about the issue.

I think i found the problem... What i can understand from the log it didnt connect with my Domoticz server. (my server at the moment is my home pc that i shut down at night. because Domoticz is still my test HA because i use the Nodo as main HA) From what i can see in the log the problems of instability started short after i shutted down my pc. (Domoticz Server) The next morning i could'nt connect to the esp with my cellphone. but in the afternoon it was working again. (my pc was running again ofcourse with the domoticz server).

This piece of the log was just before i couldn't connect anymore to my esp by entering the ip address.
