In addition to the host stack running on the module, a range of fully programmable BLE applications can be configured to run on the module. LM can develop such applications to your own requirements and/or add your own firmware to our module. We can pre-configure any applications that may require specific settings to be pre-loaded and provide modules with pre-detemined device names if required. With a battery added to the LM931 and placed into a housing, this module can also act as an iBeacon device awaiting instruction/ data, or to pass on instruction/data automatically when in range of other BLE enabled devices.
