Re: esp_wifi_scan_start() does not return mesh Information Elements

Thank you ESP_yudong and ESP-QI for your help on the matter. Disabling encryption on both sides does indeed do the trick!

How do I then go about re-enabling encryption again?

Re: How can I trigger the creation of a new mesh network, once a mesh network is full? + how to get IDs of existing netw

Hi ESP-QI, thanks for the response. Turning off Mesh IE encryption seems to do the trick - it would have been especially helpful to have that mentioned in the documentation here , given the number of views of this thread I reckon there's a large number of people out there that would find this inform...

Re: esp_wifi_scan_start() does not return mesh Information Elements

Hi ESP_yudong, thanks for getting back to me! These 30 devices are all either a root node, child node or idle (and actively searching for a network to join). Num-layers is set to 2 and max children is set to 4, resulting in a maximum mesh network size of 5. There are 6 different mesh ID's in use to ...

Re: How can I trigger the creation of a new mesh network, once a mesh network is full? + how to get IDs of existing netw

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...

Re: How can I trigger the creation of a new mesh network, once a mesh network is full?

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 ...

Re: Chain topology in ESP-MDF?

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...

Re: ESP32 WROVER MP3/AAC/(IP Audio Stream) Decoding, digital Audio Filtering and SPI Colour Display control

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.

Re: ESP32 Mesh network for sharing audio

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...

Re: How can I trigger the creation of a new mesh network, once a mesh network is full?

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...
