HI I TRIED TO RUN LORA MESH IN ESP32 AND END UP WITH THIS ERROR. PLS HELP ..

pablocaol commented 4 years ago

hello I also have the same mistake you could solve it

fmc5046 commented 4 years ago

Hi I had this problem too with the ESP32

prlombaard commented 4 years ago

@pablocaol / @fmc5046 i got the same error, i had to remove the freemem function completely from the code to get it compiled. But after compilation i have my ESPs have a kernel panic (GuruMeditation). It happens as soon as the updateRoutingTable function is called. if i remove the call to UpdateRoutingTable function then the loop() runns OK, obviously not worth anything because routing table not displayed...

@prlombaard did you ever manage to rectify this problem? I have the same issue. The exact function that it fails on is routes[n-1] = route->next_hop

I cant seem to find where this pointer is referencing, which is possibly why its crashing. If you did rectify it I would love to know.

Thanks

I'm also getting this same issue. I'm attempting to use this on a TTGO T-Beam which is ESP32 based. I have hardcoded the nodeId as 2 on one of my boards to test. It appears that the line "manager = new RHMesh(rf95, nodeId);" isn't initialising as I'm getting the "init Failed" warning. Could this be part of the issue?

enrico1036 commented 3 years ago

Compilation error (.literal._Z7freeMemv+0x0): undefined reference to __brkval', (.literal._Z7freeMemv+0x4): undefined reference to __heap_start' could be resolved changing freeMem() function to 

int freeMem() {
  return ESP.getFreeHeap();
}

elif RH_TEST_NETWORK==3

where we put this command?

Vibeesarma commented 3 years ago

how does the board create a table in the first stage?

nootropicdesign commented 3 years ago

If you want to use a test network, define the constant in your code so that the Radiohead library knows which network topology to use.

#define RH_TEST_NETWORK 3

Please study the code and Radiohead before you post comments here. These are not defects in my project. Github issues lists are not a help forum.

frd-na commented 3 years ago

@badaniels I also cannot get it to work. Removing the line routes[n-1] = route->next_hop prints the table but table does not update. Have you resolved this issue? Would appreciate some help here. Thanks!

Vibeesarma commented 3 years ago

when we transfer the message from one node to another node how to send that message using this mesh code?. I don't see the message any message send code in the mesh code.

nootropicdesign commented 3 years ago

This code demonstrates the mesh networking implemented in RadioHead. This code does not implement mesh networking. To send a message through the mesh, use sendToWait, just like this demo shows.

Vibeesarma commented 3 years ago

what kind of algorithm did you use to get the routing table?

nootropicdesign commented 3 years ago

RadioHead implements the mesh networking. It sends route discovery messages to determine how nodes are connected. If you want to understand mesh networking, study the RadioHead library.

Not sure if you had any luck again, sorry i dropped this project, life happened, will have to fire up the things again to have a look. Maybe the latest release of RadioHead fixes this issue.

Yes... Check if (route == NULL) and (route->next_hop == NULL) before attempting to access them. If they are NULL, then do something sensible :-)

Has anyone managed to compile the LoraMesh ino file on ESP32 successfully?

davidefa commented 1 year ago

Hope not to sound inappropriate... but if you want a 'super basic' example of the radiohead mesh library usage for esp32 you can follow this example: https://www.hackster.io/davidefa/esp32-lora-mesh-1-the-basics-3a0920 ( for ttgo/heltec lora boards )
