I am facing some issues with the ATZB-S1-256-3-0-C module when data is sent. In the Serialnet software it is said that ,"to ensure safe data transmission over a serial interface between a host and an MCU, it is strongly recommended to set hardware flow control". However, modules that are suported by serialnet such as ATZB-S1-256-3-0-C, ATZB-256RFR2-XPRO and ATmega256RFR2-XPRO do not have CTS/RTS pins, therefore, this is a bit contradictory, right?
These modules are based on the ATmega256RFR2, thus, it should be posible to load the Serialnet firmware on a propietary hardware with the ATmega256RFR2, shouldn't it? But which ones would be the CTS/RTS pins.
Note: I found that the ATZB-24-A2/B0 module (which is obsolete) supports UART with CTS/RTS control ,but it mounts the ATmega1281.
Thanks in advace.
