General issue report

Hi there, I am having a problem while connecting a new node to my mesh network:

• IDF Version: release 5.2 (commit cc649ea869b8c24d19ba2d94c4d3f1146cb2947b)
• Board: custom
• Setup: mesh network with one root and one node already installed, trying to connect a second node (although it looses ip also while connecting the first one
• Expected Behaviour: the root should accept a new node without losing connection to the router
• Actual behaviour: the root looses IP when the new node attemps to connect to the network
• sdkconfig: sdkconfig.txt
• log: log.txt

Is there something in the sdkconfig i should change in order the prevent this issue?

Thank you very much in advance!

1. which ESP device do you use?
2. Can you provide a demo for us to test?

Hello, @zhangyanjiaoesp I am using a custom-made board with ESP32 32E, unfortunately as this is production firmware so I can't give you a demo, but I am using a pretty straightforward approach:

1. I am using both cores (core 0 for stack threads and wifi-mesh and core 1 for my app thread (it is just a heater app which uses adc, spi some digital outputs)
2. I am using secure-boot + flash encryption (it also happens without flash-encryption)
3. Then my mesh application just calls some initilizations from esp-mdf with the default values, I know it is no longer supported but it is just a wrapper for esp-mesh so I dont think it is related.

@luisyague It should related to the application code. Because our official mesh example can works well. And according to the existing log, I can't determine what the problem is.
