Hi there, it´s me again
I am playing with another sensor which I want to run on battery with deepsleep and show measurements in the Blynk mobile app.It´s BME280 sensor
I am able to see measured values in serial monitor of IDE (connected with ESP8266-12E for the beginning) but I am not able to implement Blynk code so I am not able to see it in my phone app. I understand it´s noob task, but really coding and me are not friends
I tried to put my BME280 code into my existing code posted here https://community.blynk.cc/t/what-is-wrong-with-my-project-battery-not-lasting-as-long-as-expected/17716/40?u=helpfinder
but no success maybe some of you can help me here? Thank in advance
This is my BME280 code wotking with serial monitor
/***************************************************************************
This is a library for the BME280 humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME280 Breakout
----> http://www.adafruit.com/products/2650
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface. The device's I2C address is either 0x76 or 0x77.

My second question is related if somebody has experience with BME280 connected to the ESP8266-01 only with GPIO0 and GPIO2 (without need to solder small pins, to solder GPIO16 for deepsleep is enough I would say).
I will try to use ESP8266-07 which has more pins but I have to chedk if there is easy way to probram it without builting complex circuits with buttons etc.
Thank you
