Amber Wireless adds bonding option to AMB2621 Bluetooth Smart module

Amber Wireless adds bonding option to AMB2621 Bluetooth Smart module: Expanding the functionality of the AMB2621 Bluetooth Smart module, Amber Wireless, a Würth Elektronik eiSos Group company, has increased the packet size for payload data transmission from 128 to 243-bytes. Additionally, the compact, energy-saving wireless module has a bonding option which allows the pairing key to be stored securely in the module and a new connection with the device equipped with AMB2621 can be established without re-authentication.

The AMB2621 is a 2.4GHz wireless module, compliant with the Bluetooth Smart 4.2 standard and is available with or without an integrated antenna. Especially for the industrial wireless module domain, AMB2621 also offers the ‘peripheral only’ operating mode. This allows pairing to be initiated from a smartphone, as the device in which the Amber wireless module is integrated provides a Bluetooth Low Energy connection. Amber Wireless adopts the consumer electronics’ method whereby the wireless module stores the key of the remote terminal and renders pairing permanent. This bonding means the user only needs to enter a key with the first connection.

Thanks to the ‘peripheral only’ operating mode, the AMB2621 Bluetooth Smart module is energy-saving. The universal asynchronous receiver transmitter (USART) interface is only active once a wireless connection is established. For industrial or smart home applications there is a very simple means of developing modern operating concepts using mobile terminal devices. The ‘peripheral only’ operating mode, static pass key pairing and bonding make a secure connection easy – as familiar to users from their car hands-free speaking system.

Amber wireless was founded in 1997. It specialises in the development, manufacture and distribution of products for wireless data transmission. The company has been part of Würth Elektronik eiSos Group since 2016. Würth Elektronik eiSos provides low power ISM/SRD wireless solutions in Europe, offering efficient wireless modules in the Bluetooth or Wireless M-Bus standard as well as proprietary in the frequency ranges 169, 433, 868 and 915MHz and 2.4GHz.
