Dear Shanthi I was able to reproduce the error you reported by following your detailed description of what you have done. After comparison to commands I use and some trial and error, I found the mistake you made that lead to the error. When creating the two timer triggers, you used '100' and '500' respectively. This format does not comply the reader protocol specification but is not reported as error immediately. The error occures when trying to add these triggers which is kind of bad design. If you have the EPCglobal reader protocol standard specification, you can refer to chapter '6.5 Object Trigger'. In 'Table 7: Possible Trigger values' it sais: - triggervalue: ms=<n> - TriggerType: timer - Description: Periodic interval trigger; <n> is the number of milliseconds for the interval. With exactly the commands you used excepting 'ms=100' and 'ms=500' instead of only '100' and '500' for the trigger value it works for me and should work for you.
