I have some problem RCINPUT

i have problem …i use WFLY WFR04S

it support PPM OUTPUT ,but… RCInput is 0

how can i fix this problem…?

Do you have the receiver bound?

Should there be some jumper to enable PPM on this channel?
Are you sure PPM is output from this channel?

What does the following command output?
cat /sys/kernel/rcio/status/alive

thank you for your reply

yes i bind complete

i’m sure i test all channel … but output is same

cat /sys/kernel/rcio/status/alive output is 1

Ah, okay, most likely the problem is that this receiver does not output PPM. It says PCMS/PPM but that is used for a radio channel, not output.

oh i got it …

thank you mikhail~!
