Further finding of this pppd issue. I have noticed that in PppRouterC.nc there is an condition
#if defined(PLATFORM_TELOSB) || defined(PLATFORM_EPIC) components PlatformHdlcUartC as HdlcUartC; #else components DefaultHdlcUartC as HdlcUartC; If DefaultHdlcUartC is used instead of PlatformHdlcUartC, the telosb has no problem in synchronization with pppd with speed 38400. Does anyone has a little bit insight of this? However, using DefaultHdlcUartC, a pretty high packet drop rate was observed. Guess this is because of the difference of implementation in DefaultHdlcUartC and PlatformHdlcUartC. Can anyone has further explanation of this? Many thanks.
