Hi All, We are a company focused on WSN products development in China. We have developed a product based on TinyOS 2.X, now we are having a problem related to the power management. Here is a brief description of the problem. Hopefully we can get some help from you.
1. According to the document, TinyOS will go into sleep state when there is no task in the task queue. As we are using MP430 MPU, even in the LPM0 mode, it should be 75uA, but what we found out is about 200uA. 2. We found that in the sleep state, TinyOS still wakeup at every 2 second and do some operating system related maintenance. We don't know whether the power was used by these maintenances. 3. Can we enlarge the 2 seconds interval to save more energy? 4. Can we simplify the maintenance tasks? 5. What is the preferred approach for the power management? We need to reach 20uA level to get the required battery life. Thanks in advance, Best, Elliot Mambo Technologies Inc. (01186)431-85153859
