just tried it with an adafruit bme280 and a huzzah esp8266 and it works fine?
I live in Russia. I tried to order from your branded stuff (adafruit bme280 and a huzzah esp8266) I did not succeed. Therefore, I have only Chinese BME280 and Wemos D1 mini. It's spring here. And both my Chinese BME280 flooded with water. They are "choked". I'm waiting for the new BME280. When I get - I will describe in more detail - for some reason does not work. I tried to use the .h file of the new version and the old .cpp - so works.
Hello. I got new sensors and checked the work of your library. At the first pass of the program the NAN is issued. From the second pass everything is normalized. I solved this problem by adding a little pause (delay (100)) to the end of the begin() method.
` readCoefficients(); // read trimming parameters, see DS 4.2.2
setSampling(); // use defaults
delay(100); // Added pause
return true;
} `
I encountered the same issue after updating from 1.04 to 1.06. Adding a delay of 100ms after bme.begin() provided a dirty workaround, but wasn't really a clever solution for my code since I use two sensors and switched between them by calling bme.begin(address) periodically. I ended up creating two instances of Adafruit_BME280.
hi @rdts, are you using an ESP8266 as well? If so, what version of the esp8266 core are you using (check the boards manager). Can you post the code you are using? I just tested the bme280test example on an Adafruit Feather Huzzah ESP8266 with core version 2.3.0 and don't seem to be having any issues.
ok @rdts after looking into this a bit it seems like that delay is necessary for the first sample to be ready. I have added it to the end of Adafruit_BME680::init()
@deanm1278 Thanks, your commit should fix this. I guess this was only an issue for people who call begin() frequently from inside the loop.
The new version of the library (1.0.5) does not work with my Chinese BME280 on ESP8266. Whereas 1.0.4 works without problems. I change the address 0x76 only. In indications i see zeros only.
