Upon further investigation, the MESH_EVENT_SCAN_DONE event can only be triggered by esp_wifi_scan_start(), and only when self organised networking has been disabled. Unfortunately, the Information Elements returned by the scan do not contain any mesh data. This should not be the case, but I cannot f...

Environment - Hardware: Custom board (similar to LyraT) - Core (if using chip or module): ESP32-Wrover-B 16MB - MDF version: 3ece464 - IDF Version: `6c9c253ed` - Development Env: Make - Operating System: MacOS - Power Supply: external 3.3V --------- I'm trying to encorporate a scanning function int...

As this post is getting a lot of views but no answers there's clearly some people having the same issue (hi there if you're just lurking!). I found this post and I was lead to Espressif's example of manual networking . ----- I'm still a bit confused by some of the core mesh functionality being left ...

You can set the number of layers to 25 and max number of child nodes to 1 to effectively create a chain of 25 devices. I've succeeded in doing this, and got the better performance by also increasing the FreeRTOS tick rate to 1000Hz. I believe Espressif have a version of the MDF which allows for more...

Hi psychoacoustic,

I love the look of the visualiser you created. I'm working on somthing similar but instead outputting the data to LEDs.
I'd really interested to hear how you implimented a Constant-Q transform if it's something you'd be up for sharing.

This feature of receive audio data from bluetooth and then broadcast to other mesh nodes is not supported yet. But we have exploit a related feature: bluetooth beacon, it can be used in sales promotion, and the feature will soon be released. Hi Sam. I'm working on a project that might potentially r...

Until someone chimes in with a better solution, here's how I'm currently solving this problem. My main issue here is that the core mesh firmware is closed source and so I'm having to rely on the limited callback returns. In my event loop event_loop_cb , I create the following case: // If a network i...

(EDIT 21/05/20: This post is getting the so many hits and yet no replies :roll:) Context: I have a few hundred devices which are currently connected to a single access point. I'm sending commands, files and OTA updates to these devices, but because they are all connected to the same access point the...

With the old GNU Make build system, compiling my projects with would drastically reduce my build time from minutes to seconds. How can I do this with the idf.py CMake build system?

For context: I'd like to stream video from one ESP-32 with a Camera to another which has an LCD display. I've figured that ESP-NOW is probably the best protocol to it's lack of overhead.

What's the maximum speed that I could get out of ESP-NOW?
