Compilation fails with current HEAD about bme280 HOT 12 CLOSED

Hello Maru-sama,

Thank you for the pull.

Great catch. Mine shouldn't have compiled with those defaults in the source. What compiler are you using?

I am using platformio for development. The compiler which is used for esp8266 boards is apparently the xtensa toolchain

from bme280.

So I just downloaded the 2.1 version using platform io and compiled an empty sketch with only includes and empty setup/loop functions. I got an error calling the adafruit BME lib. I've never installed that lib. What is happening?

idesignstuff,

I had a hell of a time debugging SPI and at one point tried ada's library to check if I was init the bme properly. I forgot to pull the include out before committing. This has been fixed. Try 2.1.01.

FYI, I just compiled successfully with the latest. Adafruit is no longer called.
Rock on.

Hi,

I am having a similar issue to @idesignstuff in the above comment. I am trying to test the BME_280_I2C_Test example. I am using PlatformIO on Ubuntu 16.10 and I have a regular ESP8266 12F connected via a FTDI cable to USB.

I had to include the Arduino SPI library files and add an #include <SPI.h> in my "main.cpp" file just to get it to compile (the include in BME280Spi.cpp was not finding SPI.h).

I can upload the built code to my ESP but every 500ms it reports it is unable to find the BME Sensor. I tried the default I2C pins GPIO4 & GPIO5. I have also tried adding some extra defines as below:

#include <BME280I2C.h>
#include <Wire.h> // Needed for legacy versions of Arduino.
#include <SPI.h>
 
#define ARDUINO_ARCH_ESP8266 1
#define SERIAL_BAUD 115200
#define SDA 4
#define SCL 5

But it doesn't seem to help. I guess I'm doing something pretty stupid but C isn't my strong point ;-)

FYI - I have confirmed the BME280 is working using my Raspberry Pi and some Python code:

pi@brutha:~ $ python bme-test.py 
Chip ID     : 96
Version     : 0
Temperature :  22.97 C
Pressure :  1019.8970526 hPa
Humidity :  79.9214676864 %

TIA

Argghhh! Sorry for the noise. After trying 3 other BME/I2C libraries - with no success - I switched to different ESP chip. That one works :-( I must have a dodgy GPIO 4 or 5 on that other chip! Your example is running fine - thanks and apologies again.

That does seem odd. I will have to investigate further. I have not yet used the BME with an esp yet, so I will get to that soon.

I am glad you were able to resolve the issues.
