There is nothing particularly interesting there, sending structures and output to oled.
For now, I’m just testing how it will work for 7 days without any problems – I’ll share it!
I am currently working on a small filter, otherwise noise in the data sometimes arrives.
I also want to test the declared operating temperatures in the climate chamber (including up to -40 degrees) while searching for this camera in my city, as soon as I collect all the information, I can unsubscribe and share!)Hi, you were right, the problem is gone.
50 hours of running time without problems.
Thanks, good luck!Hello, this piece of code for getting the structure has a problem with a leak, I can’t share anything, I’ve tried a lot, what I know, I’ve run out of ideas, maybe you can help me?
I assume that the error is in the library, because the leak occurs even if the module that should send messages is turned off.if (e220ttl.available()>1) {
#ifdef ENABLE_RSSI
rsc = e220ttl.receiveMessageRSSI(sizeof(Message));
#else
rsc = e220ttl.receiveMessage(sizeof(Message));
#endif
if (rsc.status.code!=1){
}else{
Message message = *(Message*) rsc.data;
#ifdef ENABLE_RSSI
Serial.print(“RSSI: “); Serial.print(rsc.rssi, DEC);
#endif
}
}—–but!!!!!!—–
When receiving STRING – there are no such problems! no leakage, regardless of module settings, leakage only on struct.if (e220ttl.available()>1) {
// read the String message
#ifdef ENABLE_RSSI
rscc = e220ttl.receiveMessageRSSI();
#else
rscc = e220ttl.receiveMessage();
#endif
if (rscc.status.code!=1){
Serial.println(rscc.status.getResponseDescription());
}else{
Serial.println(rscc.data);
#ifdef ENABLE_RSSI
Serial.print(“RSSI: “); Serial.println(rscc.rssi, DEC);
#endif
}
}All code is taken from examples.
Look at the photo of this after 10 minutes of work, we have the following:
-start – the amount of memory at the beginning of work.
-now – is the current amount of memory.
-diff – is the difference between the last measurement and the current one.
-loss – is the difference between start (initial) and now (current) memory.
Now the loss is twice as much (2144 bytes)…After a minute of operation, after each received message from another module, 52-104 bytes disappear in memory, I read ESP.getFreeHeap().
I’ll leave the module running for a day.Hello, friend! I had the same assumptions about memory, but for some reason I discarded them, thinking that it was definitely not memory.
now the module is stuck for 18 hours of operation, the data does not reach it, the past value is = nan.
and there are two manual commands:
lora.begin – re-initialization
of serial2.flush.
if they don’t help, I’ll watch the memory.
do I understand correctly that you are talking about free esp memory? tell me the command to watch it, and I won’t make a mistake, I’ll display this value on the OLED screen, and leave the modules on for a day again.
