  Time bug in AQM?
Posted by: 41south - , 03:05 - Forum: Software Questions - Replies (6)

Hello all

AQM firmware 320-b003

I'm not 100% sure but I think I may have found a bug in the way the AQM module updates the time - or more importantly what happens when it fails to update the time.

I have just put a display on my AQM module and watching the time it sometimes is an hour out, others not. I changed the run_everyHour to run every 10 mins for debug and turned on serial debug and here is what I see. (Ignore the extra serial debug prints of 'update start' and 'Hourly update run', those are mine to track the routine entry etc)

UTC time from NTP server: 01:44:42
Local time adjusted to: 13:44:42
Hourly update run


So from the above we see that if an update fails then (because I have set a 10 minute update interval) the time is now 10 minutes slow, and continues to be despite further good ntp updates.

This explains the problem I saw when the updates are hourly, if one update fails then the time remains an hour slow until a system restart is performed.

I'm not sure if anyone else has seen this problem, or maybe it is fixed already in a later version and I just need to upgrade the firmware?

Regards to all

Colin

Hi,
I have a question re the AQM; 
When first booting how many reads should it take to initialise the CO2 sensor?
Regards
Jim

I think you can create some for your AQI WheaterDuino.

After the update v5.0_b001, the Pro2 Compact no longer connects to the WIFI network. If I flash back to V4.3, the connection is restored.

I was reading online and learning about what PCBs are and the different types that are out there. Does anyone know in what specific application you would use a single-layer PCB vs. a multilayer PCB?
