Remote AT for sleep period

[tugberk korkmaz]

Hi again Attie!

I want to change sleep period of one of my end devices to 0xAF0 (20 seconds).

Can you explain how to use xbee_conTx function with Remote AT?

Hi Tugberk,

Have you looked at the sample code?

https://code.google.com/p/libxbee/source/browse/sample/xbee1/2.remote_at/main.c?repo=libxbee-v3

You will need to specify the value as raw data. E.g:

xbee_conTx(con, NULL, "SP%c%c", 0x0A, 0xF0);

If you're still having issues please let me know.

Hi Attie Thank you for your reply

I tried your code before but the problem lies under sleep mode.

I get:

tx: -25

txRet: -17

when I send remote AT command while my End Device is sleeping.

However, I as far as I know from the datasheet, the rooter keeps the messages for sleeping devices until they are awake.

Can you help me am I missing something? 

By the way I appreciate your help thank you for your answers

I see.

I'm afraid I have little experience with sleeping nodes.

It is very possible that your message is actually being delivered, but after a longer time than libxbee is waiting for a response.

Have you checked to see? Try using XBEE_LOG_LEVEL=100 and perhaps enabling XBEE_LOG_RX and XBEE_LOG_TX.

It might also be worth making the timeout longer... you're using XBeeZB modules?

You could change the timeout values here:

line 192 - https://code.google.com/p/libxbee/source/browse/modes/xbeeZB/at.c?repo=libxbee-v3

Hi Attie sorry for late response,

I tried everything but decided to do some tricks with software. Im using Xbee coordinator with RaspberryPi and Qt. Using Qt, if the device is sleeping, I added the commands to a vector until the device wakes up. So, there will be no loss with the informations.

Thank you for your answers
