Sorry, but nothing comes to mind as to what you may have missed. Can you check out this case, and if that doesn't help either, could you try sniffing your connection using, for example, the nRF Sniffer and posting the sniffer trace here so I can take a look at the connection in detail?

Best regards,

Simon

Hi again,

Thank you for your reply, but I already based my work on that example. I actually have the same problem indicated at the end of the thread. I am able to discover the services and enable notifications but only on characteristics with a CCCD. As I mentioned before my peripheral is a devkit with the BLE_APP_CLI example that has different services with different characteristics. How should I do to read the device name for example? I also added "self.adapter.driver.ble_vs_uuid_add(MyClass.BASE_UUID)" just after enabling the ble driver. I don't know if I'm missing something.

Hi Imen

Please check out this thread (and the following GitHub fork), which shows how you can read characteristics, etc. using the pc-ble-driver-py bindings to interface with a BLE peripheral.

Best regards,

Simon
