Hi Cyril, Yes, software ACK is the default ack and you do not need to do anything special. Can you please point me to that public repository? One possible cause could be that the sender does not wait long enough for the ACK to arrive, which would be a configuration error possible in the platform/xxx/chips/rf230/RadioConfig.h.
Please do the following for me: program one mote with the apps/tests/rf230/RF230Sniffer application, connect it to a PC and run the java net.tinyos.util.DiagMsg application on it (search the tinyos archives if you run into some problem). This will list ALL packets (including the ACK packets) that the motes are sending, so we will be able to see what is the problem.
