[W-MBUS] “we have an issue about the use of the 169 Module RC1701(HP)-MBUS4 fw ver 1.10 (see the attachment) We see that we can receive up to 124 Byte while we are sending 240 byte. There is some setting we have missing somewhere? “

Max packet length (L=F6 gives 255 byte including header) is supported, but you need to increase the UART baudrate >= 56700 baud. For N mode using low RF Data Rate the module will not complete the packet transmission before internal timeout (default 2 second) takes place. Increasing UART baudrate ensure that the module have time to complete the packet TX before timeout.
