Hello all, we have problems to connect our embedded device via IrDA to a PALM. In 2004 we developed a system with an IrDA Interface to be configured with a PALM-OS application. Up to now, we got the MCP2155 with datecode 01 (REV. A) and the system works fine. Since last weeks, we got the MCP2155 with the date- code 05 (REV. C) and it is not possible, to connect to our PALM application any more.
When the connection starts, the MCP's DSR-Pin says that the link is ok and we transmit one telegram from PALM to our device. After this our device starts to answer but the DSR pin goes high and the communication stops. We tried with PALM zire31 and Tungsten E2. In the erratasheet are no hints, what the differences between Rev. A and C are. So can anyone tell me if there are defferences and which? Is it possible, that there is a difference in operating the handshake singnals ore in the timing doing so ?
