ESP-WIFI-MESH is not stable

[TRUEcabbage]

hello, i have a project relating to mavlink based telemetry system that uses ESP-WIFI-MESH, i started my development on this project 4 months ago based on https://github.com/espressif/esp-idf/tr ... mples/mesh sample code, i tested the code on esp32-wroom-32d hardware with pcb antenna, i worked well i was able to get reliable connection up to 10 meters solid, This is my project which uses esp-wifi-mesh https://github.com/WCjai/Drone-Mesh/tre ... -no-router (check branch with esp-mesh) this project is simple here is a simple illustration


i tested this even a month ago it worked fine with esp32-wroom-32d, but now when i uploaded that same code now to that same hardware it has connectivity issues, and can not able to connect with nodes or router with the hardware and code being same , but when i uploaded same code to esp32-wroom-32ue it is able to connect to routers and node, but the connection is weak after moving away 3-4meter the connection is lost and i face lot of packets loss when connection is there, i even uploaded example code too, still facing same issues


output of esp32-wroom-32d serial, with router

is there any solution?

I think it will be wise if you take another fresh WROOM 32D and try to upload the same code.

[TRUEcabbage]

i don't know what happened, i just did what you told and did full clean of my project build then uploaded the code, then it just works as normal, and i did it for the other hardware which i was facing issues with, they too functions as normal i didn't face any of the other issues mentioned before, but some esp are not connecting to mesh i have a pool of esp32 ranging esp32-wroom-32, esp32-wroom-32D from ESP32_Devkitc_v4, esp32-wroom-32d_v2.2 and esp32-wroom-32UE

esp32-wroom-32 and esp32-wroom-32D from ESP32_Devkitc_v4 together can connect to mesh but other boards ie esp32-wroom-32d_v2.2 and esp32-wroom-32UE cant connect or discover by mesh

esp32-wroom-32d_v2.2 and esp32-wroom-32UE are also same for some reason there are not detecting these two esp (esp32-wroom-32 and esp32-wroom-32D)

i have attached pre-compiler bin and elf files

but the afore mention issue still priests on esp32c3 hardware

[TRUEcabbage]

so this is todays compiled firmware of the same code, now it behaves different dropping connection, and losing packets this time, and i used fresh esp32-wroom-32UE's this time... one set with older firmware which i uploaded to this form yesterday, another set with newly compiled firmware... both behaves totally different... the one set with older firmware performs better than the newly uploaded firmware

the hardware i used is new this time
