I have got the following issue using two ProS1.
both configured at 9600bps, transparent mode, No ACK, 16bit addressing, peer to peer and connected to two micros.
the first (master) sends a 3chars packet each 100ms.
the second (slave) receives.
if I put the oscilloscope with track 1 on the TX of the Master and track 2 on the RX of the slave I noticed that randomly, for some second, the RX packets are lost and absolutely not synchronized with the TXs. sometime, this lack of receiving may reach 1s. after a while, everything returns normal.
I tried many things and also read every where but I did not find yet the matter of this behavior.
BTW, I also checked the power supply as well as reset line.
I'll really appreciate any kind of help.
