    Jumping in again, possibly completely off base here. But, is there any kind of max time between when you enable the tx, and when you send it data? Because all I see different about moving the delay loop is then enable is moved after it.
    Hi cncmachineguy, I suspect timing has a lot to do with it (although I don't kow enough to say or point to why).

    Plenty of head scratching going on here.

    As a side note, why not change the for loop to something much bigger like 1 to 250, then make the pause time of 20. This won't help the current problem, but when you are back to on interrupt you will not be trapped in the pause for near as long..
    Yes, pauses for too long are bad news for what I'm aiming at with this project.

    In my code try moving
    Code:
     E_OUT=1          ' Enable transmitter (+ lights RFEN LED on demo board)
    PAUSEUS 25       ' Allow RF stage to stabilize
    to the beginning of the
    Encode:
    block...

    Search this document for "RFEN"..

    I moved the code.

    What happens is:

    1/ If a button is pressed and released RFEN briefly flashes after the 5sec delay (no data is Tx'd).

    2/ If a button is continually pressed, nothing happens at all (RFEN doesn't light / no data is Tx'd.

    How is the voltage on the power supply/battery?

    I hope Bruce stops in and sees this as I am lost...

    I'm using a power supply set at 4.66v.

    For some reason my attachments are appearing here 'inline' rather than at the page bottom, sorry.

    The comment about dataask going high caught my eye. Maybe our timing is off a touch (not sure if or why) with the RFEN coming on and us missing data-ask going high (there is no technical reason why anything I've just typed is remotely true) Just my gut....aka....Agent Gibbs style...!

    Can you post your entire program as it stands now?

    (There's no way my feeble mind can remember all changes through a 23 page thread.)
    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
