I’m implementing a custom vendor model in ESP-IDF’s BLE Mesh stack and need to:

Force unacknowledged messages (no ACK) for group addresses (0xC000).

Suppress warnings like:

Copy
W (BLE_MESH) Not sending ack for non-unicast address
W (BLE_MESH) Replay: src 0x0001 dst 0xc000 seq 0x0000b6

I am ...

even i attached i am getting
I (193) quad_psram: This chip is ESP32-D0WD
E (193) quad_psram: PSRAM ID read error: 0xffffffff, PSRAM chip not found or not supported
E (199) esp_psram: PSRAM enabled but initialization failed. Bailing out.
I (206) cpu_start: Failed to init external RAM; continuing ...

FYI:
I am connecting to an external device, and it is currently working with an ESP32-CAM Development Board that features WiFi, Bluetooth, and an OV2640 Camera Module. The board uses the ESP32-S (ESP32-D0WD) chip.

I would like to confirm:
Does the ESP32-D0WD-V3 chip support PSRAM?

Hi ESP,
I have been successfully using DMX with UART2 on the ESP32. However, I recently included BLE functionality, and I've noticed that UART2 becomes unstable after some time.

Could you please help me understand why this might be happening? I appreciate your support.

Thank you

In this case, while subscribing, the device will still receive acknowledgments from the smartphone even if it is not connected via GATT.

I am using BLE Mesh for multiple lighting devices. Is it advisable to enable every device as a relay node?

thanks

Hi,

1.Is a Health Server model required for BLE Mesh nodes?
2.Does not using relay nodes affect message subscription?
3.Does the app developer receive acknowledgments for messages sent to nodes that are not connected to GATT?

Here are the logs from the connection using nRF Mesh:

Hi,
I am using a custom vendor model and have defined the ID as 0x0001, similar to what is shown in the attached image (nRF Mesh). Am I doing something wrong with this setup? Any advice or corrections would be helpful.
