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

Code: Select all

is there any solution?

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

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

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
