Merge Help: Door+ BME280

Puneit Thukral

Hello,
I have been struggling with this for a few days now. I have tried various permutations and combinations and the sketch does not work.
Individually both Door Sensor and BME280 work just fine but once I merge them into one sketch the node hangs.

Do I need to do anything different here?

Hi,
I had some progress with the sketch - and it works fine on the bench. On the bench, I report readings every 30 seconds but in deployment, its once in 10 minutes.

So this is happening:

The door sensor interrupt works fine. When the node wakes up after an interrupt, it gives BME readings and goes to sleep for 10 minutes and reports again. But after the first wake after sleep, it does not wake up any more until interrupt happens again.
Could someone please see what mistake am I doing in this sketch

Should I be doing a Wire.end() before sleep and then Wire.begin() after waking up. But I think its not waking up from Sleep after the 19th minute from interrupt.

Thank you

@Puneit-Thukral I have a similar sensor ( PIR + BMP280 + other stuff). I don't use smartSleep ( Since this code is old, only sleep was available ) so I can't speak about the sleep part. Maybe you could try with regular sleep just to see if brings some diference...

Regarding the BME280 (BMP in my case) , I didn't have to use the Wire.begin() / end(), and I use the same library as yours (Adafruit).

Code is bellow, in case you want to compare yourself.

/**
 * The MySensors Arduino library handles the wireless radio link and protocol

 * network topology allowing messages to be routed to nodes.

 *******************************
 *
 * REVISION HISTORY
 * (adopted from 5in1 V2.1)
 * Version 3.0 - RV -  Shifted to BMP280 sensor, added pressure and water leakage (via ROPE  https://www.amazon.com/gp/product/B004FTFQ4W/ref=ppx_od_dt_b_asin_title_s01?ie=UTF8&psc=1 ) 
 * 
 * 
 * DESCRIPTION
 * BMP280 on std SDA/SDL pins  (Temp/Pressure) 
 * LDR on pin A1:  GND ---> 10k ---> A1 <-- LDR  <-- Vcc 
 * PIR on D3 and wakeup via interrupt (in case of PIR trigger) 
 * Smoke on D2 with interrupt wake up too. ( 4n25 4K7 on buzzer, 2M7 Pullup resistor recommended ) 
 * Water Sensing cable on A2:  GND --> 100k --> A2 <--  X--X <-- Vcc  
 * (https://www.amazon.com/gp/product/B004FTFQ4W/ref=ppx_od_dt_b_asin_title_s01?ie=UTF8&psc=1)

 * Battery voltage is as battery percentage (Internal message), and optionally as a sensor value (See defines below)
