Re: Suggestion for Setting up a Mesh Network
We also need to conserve the power as much as we can, that is why we are thinking more in terms of BLE In current setup backend<->edge communication is over MQTT, and edge node translate the messages between MQTT to mesh Im not sure you will get lower power consumption with ble mesh, since every no...

Re: How to draw in the EK79007 for the esp32-p4 dev kit
This function is exactly what you need, but my previous pseudo-definition was to redraw whole display. In fact it is esp_lcd_panel_draw_bitmap (panel_handle, startX, startY, endX, endY, pixels); So, you can draw a single pixel too esp_lcd_panel_draw_bitmap (panel_handle, pixelX, pixelY, pixelX+1, pi...

Re: Suggestion for Setting up a Mesh Network
I dont know much about esp-now or other wifi mesh, but i believe they are even more limited, to 255 nodes i think? In ble mesh (esp mesh bluedroid) you can check "Directed Forwarding" feature. https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/esp-ble-mesh/ble-mesh-feature-list.h...

Re: CMakeLists.txt Questions - Errors & Components
Hi,
sdkconfig.h is created from all Kconfig files.
In some Kconfig you can find BRIDGE_EXTERNAL_NETIF_STATION option.

Re: Suggestion for Setting up a Mesh Network
No, we need to scale the solution to 40K nodes in a network (with each node 1m apart) I think you may have many issues with such designed mesh network. - it will be very noisy and may be not reliable - since you can have "only" 32k unicast addresses you will need at least 2 app/net keys and probabl...

Re: ESP32-P4 MIPI DSI commands for initializing
This is another driver which may be helpful. https://github.com/espressif/esp-bsp/blob/master/components/lcd/esp_lcd_lt8912b/esp_lcd_lt8912b.c It is MIPI to HDMI chip and i see it a good source of code to learn. Yes, the mipi is not documented yet, but it is fairly new interface on esp32, so we have...

Re: esp-tls: couldn't get hostname for :example.com: getaddrinfo() returns 202, addrinfo=0x0
There is not enough data to help with the issue.
Is the connection success before you call "getaddrinfo"? And by success, i mean you get IP address from DNS or set static IP after connecting to router.

Re: How to address a node in ESP BLE Mesh
There is few types of ble address, most important and mandatory unicast address, which is 16 bit and has nothing to do with mac address.
Usually it is assigned by provisioner, although it can be assigned by manufacturer (hardcoded address), but it is not recommended.
