Hi,

 

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Note: I found that the ATZB-24-A2/B0 module (which is obsolete) supports UART with CTS/RTS control ,but it mounts the ATmega1281.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.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

I had this same problem recently and found this post with no answer so I decided to dig into the SerialNet Source code I had. BitCloud v.3.1.0; SerialNet v.3.0.0.  

 

CTS is an output and is on pin 15 of the module (PD5).

RTS is an input and is on pin 14 of the module (PD4).

DTR is on pin 35 (PE4), but they are not supporting it in the new SerialNet firmware for some reason.

These are the same processor port pins as the old ZigBit ATZB-24-A2 Module running BitCloud v.1.14.0; SerialNet v.2.7.0
