I am experiencing a problem where my core suddenly gets into a state where it has no variables or functions exposed. The core is still flash-able in this state, but it is causing data loss for my data monitoring project! I am running a script that contacts the core every 5 minutes to collect data. …

Hi @ubermensch ; I am guessing that there’s some interaction between the code you wrote and the background code that’s handling communications; would you mind sharing your code, either by pasting it here or by pasting it in a gist and posting the link?

What type of interaction could it be? Is this a known failure mode? In what circumstances does it happen? Have you ever seen this issue before? It would seem odd that my code that is running for hours could have the effect of suddenly removing variables when there is not even API for removing variab…

In the gist, it looks like you intend to have curly braces around the indented code in lines 108-118: https://gist.github.com/aznel/10cf0690f7cd6168828e#file-gistfile1-cpp-L108-L118 gistfile1.cpp // This #include statement was automatically added by the Spark IDE. #include "idDHT22/idDHT22…

Hi @ubermensch , It looks like we’re also talking about this over email, so I’ll post my response here: It seems like the program you’ve been running registers more than 4 Spark variables (I counted 8), 4 I believe is the limit. I’ve also noticed your core is frequently disconnecting and reconnecti…

I suggest trying this also : [image] TCPClient + idDHT22 = Hard fault Hi all, I’m trying to get my spark core to send temp/humidity to Xively. The 2 parts in my loop separately run correctly but combined I see “Connecting to Xively…” in the serial monitor, a SOS Hard Fault (sos 1 sos) a…

Thanks for the link @Rockvole . @ubermensch After some discussion with the Spark team, it sounds much more likely to be a firmware issue. Also the number of variables allowed is ten, as can be seen below in USER_VAR_MAX_COUNT, so your 8 should be good. If anyone else encounters this issue, do let u…

Registering too many variables should not cause the variables to exist for 16 hours and then suddenly disappear. The same is true for the internet connection dropping out. Also, if these were the cause of the problem you probably would have seen this situation before? This code posted is the minima…

Heya @ubermensch , The cloud asks for a list of variables/functions from your core two times, once about 1.25 seconds after connecting, and then again about 60 seconds later if the first time failed. If you’re blocking during setup, your firmware will miss the first call, and if you have random del…

You might want to try the newer one : [image] [Submission] Updated Non-blocking Interrupt Driven DHT Sensor Library I have published an updated version of the DHT interrupt driven sensor library. It now supports DHT22 and DHT11 sensors. It has been published it as PietteTech_DHT in the…
