But in my application i'm only using 116 bytes of payload.. So the maximum packet size is header+payload which equals 126 which is within the limits only....... I tried to run the application with less packet size, but the error still exists. with regards Siva 2009/3/4 Ittipong Khemapech <[email protected]> Hi, > > According to the error message, I think your payload is too long.
