Read Data From External Serial Interface; Send Radio Frames - Michael MBWBLUE Mode D'emploi

Read Data from External Serial Interface

After having send data to the external serial interface, the MBWBLUE waits the TO (timeout) time for
getting an answer. If there is an answer it can be read using this command (all bytes hexadecimal):

Send Radio Frames

The MBWBLUE devices are bidirectional radio transceiver, thus, capable of sending radio frames,
also. In general, the configured radio frame is sent after a radio frame from the respective
consumption meter has been received. Therefore, the command below is not directly sending the
radio frame but stores the radio frame to the internal buffer of the MBWBLUE.

Transmission speed (chiprate)
The registers for the transmission speed are calculated as shown below:
S[2,0] = 65536 - (12000000 / chiprate)
Examples:
100000 chip/s: S2 = 00, S1 = FF, S0 = 88
32768 chip/s: S2 = 00, S1 = FE, S0 = 91
(not supported for FW version 3.xx)
Link layer address of the consumption meter to send the radio frame to.
A0 = LSB of manufacturer code
A1 = MSB of manufacturer code
A2 = LSB of serial number
A3 = LSB+1 of serial number
A4 = LSB+2 of serial number
A5 = MSB of serial number
