ESP32-WROVER-B - PSRAM not working at 80MHz

Hi folks, I've searched around for this issue and found nothing similar, so I thought I'd make a post. I've put many 16MB ESP32-WROVER-B modules into production which have no problem running both the Flash and SIPRAM at 80MHz. However, for a new production run, the 16MB ESP32-WROVER-B modules can ru...

Re: Send file over ESP-Mesh network (ESP-MDF)

HI there, yes it is possible. I've been able to transfer audio files over the mesh network. I essentially looked into how the Mesh OTA works and adapted it to send byte data which is then saved to an SD card on the receiving device.

Re: Difference between ESP-MDF and ESP-IDF mesh application examples

The core mesh functionality is contained within ESP-IDF. ESP-MDF is a framwork which abstracts a lot of that functionality into pre-made funcitons, like Mupgrade, Mwifi, Mconfig etc. to save you the hassle of doing things manually. If you compare the ESP-IDF manual networking example to the contents...

espressif guys you will never win with such poor support to developers, most of the topics at forum is dropped at some stage or just unanswered.
What a shame
You know this is wonderfully ironic looking back

Re: ESP-MDF Development workflow

Hi Twinstar, You can use Arduino as an ESP-IDF component , this would then allow you to import any Arduino libraries of your choosing. Bear in mind that the Arduino component only works with ESP-IDF-v3.3.2, V1 release of ESP-MDF and V2 Release of ESP-ADF. This is similar to the tech stack we use for...

Re: Mesh network with ip connectivity to nodes

Assuming that your actual goal is to address individual devices, if you use something like MQTT or OSC which use URL-style messages, you can include the desired mesh address as the first term of the URL. Your root node should strip this value from the start of the message and use it to send a messag...

More information on recent demo from Espressif (looking for ways to speed up my mesh network)

I recently saw the demo of 256 lights on the Espressif Instagram page and would like to hear some more details on that from Espressif if that would be at all possible? I'm especially interested in: What sort of network topology was used? i.e. how many layers and children per layer (Given that only o...

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 ...
