Dear Team,
I have recently acquired NRF54L15 Development Board for evaluation and from Day 1 experiencing issues with BLE.
I am running simple Zephyr-based BLE Peripheral test application from NRF Connect SDK samples which advertises simulated Heart Rate and at the same time provides access to a couple of GATT services.The issue I am experiencing is when trying to connect to the device from NRF Connect or LightBlue apps from my iPhone - with both apps the device is extremely sluggish during the connection (in debug mode I figured out it goes through non-stop connect/disconnect loop) and I can only connect and see services in may 1 out of 5 cases after approximately 10-15 seconds waiting for the connection to happen.
Next to me I have my old NRF51 Dev Board running Bluetooth stack exposing several GATT services and it always connects immediately and with 100% reliability.
Can you please help to understand what is the issue and wether I should be considering older Nordic chipset for my new device instead?
I thought it would be a good idea to use the latest chipset with all new features and much better power usage, but I might be mistaking.
Is this a Zephyr/Softdevice related issue or something is wrong with the chipset itself?
Thanks
WBR,
Alex
