Abstract: A network (1) is described. The network comprises a plurality of electronic devices (9) in data communication relationship with a data collection unit (4) having a wireless network access point. Moreover:
- each electronic device(9) comprises a wireless communication unit (13; 13.j) featuring a station mode function (SM) and an access-point mode function (APM);
- each electronic device (9) of a first set of electronic devices is directly linked, through the station mode function (SM) of the respective wireless communication unit (13), to the wireless network access point of the data collection unit (4).

Abstract: A method for recognising a communication protocol of data packets (M1, M2) travelling over a communication bus (20).
The method comprises a CRC check procedure (PCRC1, PCRC2) for processing a data packet (M1, M2) travelling over said communication bus (20), said CRC check procedure comprising:
- calculating a first checksum string (CKS1) by processing the payload portion (S1) of said data packet, according to a first CRC-generation engine associated to said first communication protocol (PR1);
- calculating a second checksum string (CKS2) by processing the payload portion (S1) of said data packet, according to a second CRC-generation engine associated to said second communication protocol (PR2);
- comparing with said first and second checksum strings (CKS1, CKS2) with the CRC portion (S2) of said data packet.
