Method, device and computer program product for protocol selection

A method implemented at a second device, comprising:

• determining, based on hardware information of the second device, protocols supported by the second device;
• receiving, from a first device, a request for connection establishment, the request for connection establishment being transmitted using a target protocol, the target protocol being determined based on priorities of protocols supported by the first device;
• and
• transmitting, to the first device, an acknowledgment to the request for connection establishment based on the protocols supported by the second device and the target protocol.

A first device, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, the memory having instructions stored thereon, the instructions, when executed by the at least one processor, causing the first device to perform acts including:
• determining, based on hardware information of the first device, protocols supported by the first device;
• selecting a target protocol from the protocols based on priorities of the protocols;
• and
• transmitting, to a second device, a request for connection establishment using the target protocol.
