Exception 28

[Bonbon604]

Hi,

does anyone know what coud be the issue?
It happens in line "connection.init();"

Exception 28: LoadProhibited: A load referenced a page mapped with an attribute that does not permit loads Decoding 9 results 0x40205d7f: String::reserve(unsigned int) at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/WString.cpp line 192 (discriminator 4) 0x402060a8: String::concat(char const*, unsigned int) at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/WString.cpp line 353 0x40100cc2: umm_free at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266\umm_malloc/umm_malloc.cpp line 688 : (inlined by) umm_free at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266\umm_malloc/umm_malloc.cpp line 667 0x40204aea: operator+(String&&, String const&) at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/WString.h line 404 : (inlined by) TR064::initServiceURLs() at C:\Users\me\Documents\Arduino\libraries\TR064\src/tr064.cpp line 129 0x40207308: esp_delay__delay(long unsigned int):: > at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/coredecls.h line 69 : (inlined by) esp_delay__delay(long unsigned int):: > at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/coredecls.h line 78 : (inlined by) __delay at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/core_esp8266_wiring.cpp line 39 0x40201a2f: setup at C:\Users\me\Documents\Arduino\home-indicator/home-indicator.ino line 159 0x40206dc8: loop_wrapper() at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/core_esp8266_main.cpp line 255 0x40100fed: cont_wrapper at C:\Users\me\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.1.1\cores\esp8266/cont.S line 81

Please post a debug verbose output and your Fritzbox version.

[Bonbon604]

Sorry I'm very new at esp and also in programming. What is the debug verbose output? 😬
Here is my fritzbox version:

Can you check if you get anything if you visit http://192.168.178.1:49000/tr64desc.xml in your browser?

[Bonbon604]

yes, i got an xml. What should I search for?

[Aypac]

Can you post the first couple of lines? And to be sure, what version do this library do you have installed?

[Bonbon604]

1.2.2 is installed
the library works fine with esp32 but not with esp8266 :(

[Aypac]

Ok, the XML seems fine.
The note that it only works on esp32 is very helpful, then I have an idea what direction to investigate into.
I looked at the code; what surprises me is, that these lines:

[TR064][initServiceURLs] 0 readServiceName: @ readServiceUrl:

seem to indicate, that the XML is faulty (which does not seem the case) or some other error retrieving it (which from your comment could have something to do with the wifi library difference between ESP8266 and ESP32.
However, if that was the case, it should stop after finding a single empty one. But it does not - which eventually leads to the µC crashing, because it can only hold a max of 100 lines.
So why two questions we have to figure out:

1. why does xmlTakeParam return empty results? Does it get empty input to begin with?
2. why does the code not stop then? Does xmlTakeParam return the proper 'false' flag?

I have to see when I can find the time to investigate this further.

[saak2820]

In the meantime, you can execute the commands without loading the xml.

// without loading available services through init() you have to set the url
// you find the url in the XML file http://192.168.178.1:49000/tr64desc.xml

Example in caller.ino
if(connection.state()<0){
// connection.init();
}
connection.action("X_VoIP:1", "X_AVM-DE_DialNumber", params, 1, req, 0, "/upnp/control/x_voip");

Hello,
I have got exactly the same problem as Bonbon604 described (even with a different fritzbox):

1. I am using a WEMOS Lolin D1 mini.
2. the Fritzbox dumps:

3. the WEMOS replies (using VERBOSE):

4. the Fritzbox indicates correct connection to it on Wifi level

I have tested several programs (c't, Reichelt, the examples in this repository), but all show the same problem.
Also the former version of this library, the same.
Finally I discovered, that the program stops working (with the above results) a the function call of the "connection.init();" in line 93 of "DECT_Caller".
When it scans the reply from the fritzbox (see point 2), it seems not be able to find the information in the tags. Maybe there is no stream to be scanned...?

How can I discover the issue? Is there a hardware which has been proven to work with this library and a fritz.box 7490?

Any help to get a running system would be appreciated.

Thanks
Andreas

I'm actually working on debugging this right now. I think I found the issue actually. With a bit of luck I can upload a fixed version in a bit. Looks like I messed up the pointers to the http stream when integrating the PR for https.

[Aypac]

Can you test with the commit d4324bd on the develop branch? I think it should fix this issue.
