Lindon, UtahIndustrial wireless networking vendor MaxStream is releasing a firmware upgrade for all of its IEEE-802.15.4-enabled XBee and XBee-PRO products (click here for previous eeProductCenter reviews). The XBee-PRO, for example, is a 2.4-GHz module that runs about 60-mW in the ISM (industrial, scientific, medical) portion of the band.
The 802.15.4 standard serves as the RF backbone for the increasingly popular ZigBee wireless protocol. The firmware update now supports features such as A/D (analog-to-digital) conversion, digital input-reading, and encryption.
With the latest 802.15.4 firmware, the XBee product family is now able to automatically take analog and digital input readings at user-defined sampling rates. Digital inputs can also be reported during transition occurrences, or through cyclic sampling.
In between sample periods, these radios can be configured for Sleep modes that draw less than 35-uA, making them useful in battery-powered applications. Also helping to conserve power and bandwidth in data-acq applications, multiple analog and digital inputs can be collected before they're wirelessly transmitted.
The firmware upgrades also impart 128-bit AES (Advanced Encryption Standard) encryption. It gives you a secure and reliable network connection for applications dealing with sensitive or critical data.
The beta release of the latest firmware will be available for download this month, with a full release planned for July.
