gfit_fep_send_manufacturer_specific_page (0xB3)
Command: Instruct the module to send a manufacturer specific over the ANT+ FE -C channel. The
manufacturer specific page will replace the page to be tr ansmitted; it is not recommended to insert
manufacturer specific pages in a short rotation interval as that may affect the transmission pattern for ANT+
FE-C. This command should only be called once per channel period of the ANT+ FE -C channel; the application
can use the EVENT_TX as cue to send the manufacturer specific page, or send the command based on
asynchronous events (e.g. button). Valid manufacturer specific pages numbers are 0xE0 to 0xFF.
Valid State: READY, IN USE, FINISHED
