DESCRIPTION WT41-E is a long range class 1, Bluetooth® 2.1 + EDR module. WT41-E is a highly integrated and sophisticated Bluetooth® module, containing all the necessary elements from Bluetooth® radio and a fully implemented protocol stack. Therefore WT41-E provides an ideal solution for developers who want to integrate Bluetooth® wireless technology into their design with limited knowledge of Bluetooth® and RF technologies. WT41-E is optimized for long range applications and since it contains a RF power amplifier, low noise amplifier and a u.fi connector for an external 2 dBi dipole antenna. With 115 dB radio budget WT41-E can reach over 1 km range in line off sight. By default WT41-E module is equipped with powerful and easy-to-use iWRAP firmware. iWRAP enables users to access Bluetooth® functionality with simple ASCII commands delivered to the module over serial interface - it's just like a Bluetooth® modem.
