nrf52840 as BLE peripheral

[Liam Richardson]

Hello,

I'm working on a BLE app on an Arduino Nano 33 BLE, which is equiped with an nrf52840. I'm struggling to increase my BLE transfer speed ( i think due to the limitations of the arduino library ).

At the moment i am updating a GATT caracteristic value with notifications, on my arduino (peripheral device) and reading the value changes from a central device (PC). PC is equiped with Bluetooth 4.2.

The problem is, i cannot change the carateristic value very quickly.

Can i do this more quickly by writting to the registers ?
Any other solutions for faster BLE transfer with my setup ?

Thanks

If there is no configuration API available in the Arduino library, you will have to modify the Arduino library itself. I recommend contacting the developers of the library to get help with this.
