3.1.7 WLAN Interface HERMES 2.1, 2.1
HERMES 2.1 does not support any Bluetooth. The WLAN solution of Hermes 2.x based on CWM-
07/71 modules manufactured by WNC. CWM-07 and CWM-71 modules provide the same
functionality are pin compatible but are base on different SoC. CWM-07 is based on Cypress SoC
BCM89342 and CWM-71 on Cypress BCM89359. Both SoC have the same die but different
packages.Therefore both modules use the same configuration files. Modules are calibrated during
production and calibration process and data are stored in the internal OTP memory. There are two
variant of CWM-07/71 modules, CWM-07/71-25 and CWM-07/71-2255. The table belowe provides
mapping between Hermes’s version, variants and used modules.
