Hi,

Apologies for the delay answering. It seems that the noise sensor is causing interferences in the interruption pin. Please fill the RMA form and out tech support team will contact you to solve the issue.

No worries. Raised a RMA.

WASP P&S Smart City Pro - 271CBC32C8913E87
Supplier – M2MConnectivity

I tested the same sample code using a different noise sensor (serial # 000289) but got the same error as before. I am wondering if it is the WASP issue (e.g. plug A circuit) rather than noise sensor issue.

Hi,

Yes, it could be an issue in the Smart Cities PRO board. Anyway, we prefer analyse both devices, node and sensor, to make sure they work together.

Hi Team,

I didn't hear from the tech support team for my RMA. Could you advice the next step?

Cheers
CK

Meantime, I want to understand the difference between the following functions when it comes to battery consumption, life time of sensors, any other parameters

Code: Select all

delay(300)

Code: Select all

PWR.deepSleep("00:00:01:00", RTC_OFFSET, RTC_ALM1_MODE1, ALL_OFF);
Based on above these, do you recommend to use a delay() instead of a deepSleep() for 10 minutes between data collections and posting to AWS through Bridge when I have the following sensors connected to my WASP?

Code: Select all

    Socket A - Noise Level Sensor
    Socket B - Carbon Dioxide (CO2)
    Socket C - Carbon Monoxide (CO)
    Socket D - Particle Matter (PM1/PM2.5/PM10) - Dust
    Socket E - Temperature + Humidity + Pressure
    Socket F – Luxes (Luminosity Probe)

Hi,

We always recommend using deepSleep() function to decrease battery consumption. The current consumption of Waspmote in this mode is 33uA while using delay() the minimum current consumption could be is 17mA (if the sensors and radio module are OFF, if not the consumption is 17mA + consumption of the sensors + radio).

In the case of your configuration, we recommend keeping the CO sensor ON to get better accuracy and using the following deepSleep function to avoid to turn OFF the sensor.

Code: Select all

PWR.deepSleep("00:00:01:00", RTC_OFFSET, RTC_ALM1_MODE1, SENSOR_ON);

Thanks for the clarification and the links to documents. It helps a lot. However, I not sure how to solve the issue with the noise sensor interrupting the RTC. Should both noise sensor and WASP be returned to M2M for troubleshooting?

Hi,

Apologies for the delay answering, we have just informed our colleagues to send you an email with the instruction to return the device for repair. It seems a hardware problem in the P&S and it's needed to analyse it fiscally.

Regards
