1. A method for wireless data transmission between first and second transmission participants comprising the steps of:
- alternately a first protocol and a second protocol are used for wireless data transmission between the first and second participants, wherein;
the first protocol serves for unidirectional data transmission and the second protocol for bidirectional data transmissionthe first participant is a field device of process automation technology for logging and determining process relevant data;
the first protocol serves for the transmission of data from a memory unit provided in the field device to the second participant in a first interval,the memory unit is connected with an operating electronics of field device;
the second protocol serves during a second interval for bidirectional data transmission for ascertaining data, which is to be exchanged from the field device to the second participant by the means of the first protocol, andduring a third interval, the data are written from the operating electronics of the field device into the memory unit.
