pc-ble-driver-py NRF_ERROR_NO_MEM issue

[lukan]

Hello everyone,
I am working on a project where I am connecting a peripheral device (using nrf52832) to a central device (nrf52840 dongle). I am utilizing pc-ble-driver-py for connecting to the peripheral, notifying, sending, and receiving. However, I encounter the following error after initiating notification from the central device:

pc_ble_driver_py.exceptions.NordicSemiException: Failed to ble_vs_uuid_add. Error code: NRF_ERROR_NO_MEM

I saw some threads where they have adjusted the RAM_SIZE that resolved this issue. How can I do this in pc-ble-dricer-py??

Thanking you in advance.

Hi,

The issue could be that the number of vendor specific UUID's are not configured high enough. Try enabling the driver with a higher BLE_COMMON_CFG_VS_UUID count (see here).

Hi Einar Thorsrud ,

Thank you so much for your response. I already tried it but got the same error. could you please give some example for the solution. what value should work?

Hi,

If the problem is the VS UUID count then I don't have other suggestions than increasing the number. Could  you check (perhaps just by logging) how many times you ble_vs_uuid_add is called? I ask partially because it is a bit suprising to me that you see this when notifications are enabled. I do not see why you would add a new base UUID at that point.
