I expected a Serial2.setConsole(true) should help, however this results in :
Uncaught Error: Function "setConsole" not found!

Serial2.setConsole(true); -
Gordon, thank you. I could not get it to work. I will be away 3 days.
I was seeking a solution to get this simple test snippet to run, when not connected to a USB port of a computer. As I understood, the Serial port will be on USB by default. And on Serial1 by Default if unplugged. So this blocks my device (HM10). So I would like to set to USB or Serial2. I could not get it to work. I ll check later on it.Serial=Serial1 Serial.setup(9600); Serial.on('data', function (data) { console.log(data); if (data==='1'){ LED1.write(1); Serial.print("test\n"); } if (data==='0'){ LED1.write(0); } if (data==='d'){ LED2.write(1); Serial.print("sensor: t="+temp_act+", p="+press_act+", h="+hum_act); LED2.write(0); } -
If connected to the usb and ide the Serial obe works just fine. How exactly trick Serial1 to allow the onData to work as in ide if powered from external power source?
-
Ic yes that makes sense otherwise reflashing could be an option
-
I get an error telling me command not found.
I use the big one -
i have not closed the sockets. i declared them to null. this may not have been enough. however this may be part of networkjs. i cannot test further i am abroad, the next 4 weeks. thank you for your kind support so far.
-
thank you very much. eventhough i resetted the sockets, the leak was still there. i expect the netcallbacks to leave external references (to the sim900 code) in the networkjs. closures are prone for memory leaks but most websites do not run above 1h, so nobody notices it.
-
thanks for the feedback. could you send me your code as well? Do you have any? (info@sp33c.de)
I try to sync with gordon, but I am abroad a couple weeks, propably offline. -
per reconnect my code is leaking 200 memory units (a 20bytes?)
-
I just noticed, the SIM900 library is memory leaking, maybe du networkJS.create(netCallbacks).
Upon a repetive call on reconnect old references aren't getting collected with garbage collection, I assume old references are still being kept externally.
Could this issue be due to the networkJS library? Or is it due the SIM900 library only? -
I updated my version to get rid of self caused memory leaks, I use the immediate return for timeouts. Thanks to the fix to the SIM900 module it is so far quite stable.
Additionally I set the SIM900 baud rate to 9600. Additionally I pull jobs out of resources with the max=1 parameter, means get only as less data as possible.
Memory seems stable so far.
I put the code online: https://github.com/afitterling/espruino-projects2/blob/master/RemoteWateringSystem.js
The cariots module can now handle wrong JSON and will reject the successful call:
https://github.com/afitterling/Espruino-Modules/blob/develop/carriots.js
this is the result of the status push at call 104.{ "stats": { "process": { "stackEndAddress": 536959420, "flash_binary_end": 376280, "flash_code_start": 134234112, "free": 2875, "flash_length": 393216, "usage": 2225, "total": 5100, "flash_start": 134217728, "history": 1753 }, "errorFlags": [], "requests": 104, "errors": 0, "resets": 1 } } -
i am experienced with garbage collection issues, it should theoretically never be the case to run out of memory if constantly destroying references my self carefully. also not json is an isue as after processing the objects are nulled.
i may have to rething the overall model of that piece of hardware.
-
@allObjects the blownup json is due mainly of infrastructure. carriots is a great iot platform. of course i can write the whole platform myself and being leaner. but i rely on such infrastructure for inter device communication. i like there way. i think the espruino device should be capable of handling such simple things. the productive response data is a bit leaner just carrying two values, cycle (watercycle) and time. also i use the max param to limit the get to one response entry at a time.
carriots doesnt represent a full schema but all you need to be able to handle different devices and logik. one optimization point can be to put the logic into carriots and have not a autonomous device anymore.
the overhead to deal with csv isnt really an advantage.
-
@jonreid yes, i knew about it and my status post requests are publishing the memory free. may i ask how do you reboot? what command?
hm... my code is not that big, actually at any point there shouldn't be a less memory state. i even taking care about intervals and timeout myself. it might due to memory leaking somewhere else.
-
I think @Gordon is right:
"FIFO_FULL", "LOW_MEMORY" ] } } } Uncaught SyntaxError: Got ID:total_documents expected ',' at line 3 col 3 {"total_documents":3,"result":[{"_id":"579bc6ad5c5d751b7e537... ^ in function called from system -
-
Amazinly doing so.. it seems to works! I just put the max=1 param out. As of today a collection length of >3 broke that.
@Gordon To the FIFO issue.... may it be a wrong canditate. I was noticing, the E.getErrorStats always returns FIFO_full on any request. But it is going to be erased later on.

in the above log from the example it looks like that the response string itself handed into JSON.parse is not valid json anymore. It has passages like:
e":"Commander@afitterling.afitterlinÂg","data":{"This":"Is a JSON example","Carriots":{"texfitterli ] "+D,0,900:t\":\"str\",\"at\"So I came to the conclusion the SIM900 mixed it up(?)
-
I use the maximum baud rate on the SIM900, can this be a cause?
-
I am using the Pico board.
I run it currently over usb but additionally with an external power supply, as the usb connection is only for debugging purpoises. I sometimes pull off usb.If the document gets parsed by one the total_document is there every time. If however the document getting JSON parsed is only truncated this is missing.
I could successfully reproduce that the error occurs only if a certain treshold of response length is tresspassed. And the response string from the hardware seems truncated.
I looks as if it receives only a limited amount of bytes? But there is only one callback? So my assumption was the callback gets called with an incomplete set of data, that itself will be passed in to the callbacks/promises.A good thing. As I understood now at least the source of error, I could so far fix it with the max param that carriots provides. I pick only one job at a time. If this works for 7d/24h I'll be glad. My garden is in a remote area very far away. :-)
-
I believe I shouldn't bother about this behavior. I just seen, the carriots io supports the max parameter. So I will get only two at a time. And my code will be fixed. :-)
-
It is wired once more carriots wants me to send content-length on get....
-
I accidentally also put my debug output from the request in their above? Should I take it out.
