Re: Restart ESP8266

I use mqtt to start and stop some measurements the ESP is doing.
But after 2 times starting the measure the ESP crashes. So I want to restart it after every measurement.
Thanks vor the help, i will try this =)

Restart ESP8266

Hi,
is there a way to restart the ESP from the code?
I know that there is the reset function in the machine library.
But I don't think that it is what I'm searching for.
I need a function that shuts the ESP completly down like pulling the plug.

Re: ESP8266 stops working

Thanks for the ideas. while testing them I didn't find anything, so I testet around and found a loose connection. That was just "active" in real usage not in testing mode.

ESP8266 stops working

Hi, I'm using my board to read data from a BNO055 and send it directly to a server. I read the values in a while-loop and send them every 10 values via mqtt (umqtt.simple). My problem now is, that the board stops sending values after an random amount of seconds, sometimes it stop after a few secons ...

Re: Powering ESP8266 from Adafruit PowerBoost 500 Charger without USB

I'm using the NodeMCU v2 board.
I've connected the Pins GND and 5v from PowerBoost 500 to the vin and GND pin on esp8266(next to the resetbutton).
So I also expect the ESP board to run, but it is not doing anything

Powering ESP8266 from Adafruit PowerBoost 500 Charger without USB

Hi again,

it looks like there is a 5v input Pin on the ESP-Board so I want to Power it without USB to save space.
I managed to tap 5v from the chargers pins, but the ESP doesn't do anything.
Does anyone has an idea why I'm not able to power the ESP like this.

Best
Matthias

BNO055 calibration problem

Hi, I'm trying to use the mentioned 9DoF-Sensor with a ESP8266. For that reason I use this driver ( https://bitbucket.org/thesheep/micropython-bno055). My problem is, that the BNO055 is calibrated, but the values from the accelerometer and for the linear acceleration are (horribly) wrong. >>> s.acce...
