BLE 4.2 softdevice s132 v 2.0.0 and client

Hi all,

i have a question about the communication client and server. I'm using for my project a nrf52 and softdevice s132 v2.0.0, reading the datasheet i can understood that it use ble 4.2 version 2.0.0.

My question is, our device can communicate only with server that support ble 4.2 and higher version? or it can communicate also for example withe ble version 4.0 (for example)?

Thank you, -Anna

  • Hi,

    Yes, the versions are inter-operable and compatible. All features in the newer BLE versions need to be negotiated between the Central and the Peripheral before they are enabled on the link. If only one device support a feature, the negotiation will fail, and the feature will not be enabled. But the connection will still be valid and they will be able to continue to communicate.
