  • I recently purchased the RN-41 bluetooth module. setup was somewhat a breeze and the range is fantastic. I have everything working perfectly except one issue I cannot seem to resolve. I need to use the general purpose I/O (just one of them). I chose pio7 and set the pio register to make 7 an output upon powerup. my software in CMD mode sets gpio 7 high (which is pin4 on this module). Once the cmd is issued ,the pin raises to 3.3v (as expected) then fluctuates from 1.1 to 3.3v in a pulsing manner. The DC level isn’t a stable logic high. Has anyone else had this issue? If so, is there a solution or something I am overlooking in the setup? perhaps low power mode or something like that?

    Any help would be appreciated as this is holding back my project.

No public wish lists :(
