I am currently doing a project whereby a user's position inside a building is determined by the RSSI on a PDA from several bluetooth nodes around the building. As part of this project I want to alter the power output of the bluetooth nodes around the building to get various RSSI values at different power outputs to increase the accuracy of the system.
Is it possible to access the LMP from InTheHand or by other means to:
(a) turn off or reduce the power to zero of all but one node
(b) set the remaining node to 25% power, 50% power, 75% power and 100% power to get the RSSI at these different power levels
(c) repeat this process for al the other nodes etc
I have found references to LMP_incr_power_req , LMP_decr_power_req , LMP_max_power , LMP_min_power (http://www.palowireless.com/infotooth/tutorial/lmp.asp) but cant find how to use them. The PDA I am using runs Windows 5.0 and I am using the latest version of InTheHand.Net.Bluetooth.
