Iam using XBee SX 868 for communicating between my drone and transmitter.
I Have coordinator connected to laptop and router connected to my drone.
i got the communication 6sec delay.
when i change mode stability to Alt hold to Land i got 6sec delay
When i give Throtle i get 6 sec delay.
Can you say ASAP why it is happening and how to rectify it. Do i need to change any values in Xctu or something else.
Baurd rate 57600.
I would suggest setting the DL and DH values of both radios to match the SL and Sh of the other. I would also suggest setting the TO command to 0x40.
Thanks for the response,
But i have gave all those parameters before itself.
Even after i gave these parameters the delay is showing 6sec.
What is the CM you are using?
CM is channel mask i kept it default. The CM Iam using is 3EFFFDFF
My BR RF_Data rate is 80kbps
What I would suggest is removing the radios from the device and running a range test. Do you see the same delay from the radios when doing the range test? If not, then it is not the radios causing it.
As you suggested i had tested the devices. i observed the same delay.
BD Baud Rate 57600 57600 
D2 DIO2/AD2 Digital Input  Digital Out, Low 
D6 DIO6/RTS Disable  RTS flow control 
D7 DIO7/CTS Digital Input  CTS flow control 
IR Sample Rate 2000 0
P2 DIO12 Disable  Digital Out, Low 
IC DIO Change Detect 4 8
TO Transmit Options 40 40
can you suggest me which parameter gives delay.
What is the SP, SM, ST and SO vales set to?
I apologize for late reply. I never changes these parameters these are the values in both coordinator and router
sp-sleep time 190
sm-sleep mode normal(0)
st-wake time 1F40
so-sleep options 2
My question is is there any parameters that initiate’s delay in the module
I am not seeing anything on the radio that would cause it. I would suggest removing the radios out of the picture and run a wire between the two and see if you have the same delay or not.
