PIC or xbee times out after Tx 504 bytes

[Ioannis]

From a very preliminary test I did, the receiver of the XBees is very susceptible to saturation. I had to move the modules 10-15 meters away to work properly. I know this seems irrelevant ot your case but just keep it in mind.

P.S. Are you going to make a ZigBee network?

the distance factor could have been an issue and one to keep in mind. thanks.

i have the xbp24-zb's for another project for a ZB network.

this current one is using the "802.15.4 series I" xbee's.

i wonder if there is a config parameter that helps with the saturation issue for short distances? would you know?

[Ioannis]

Just drop the RF power to the minimum. But ifdistance is less that 5 meters the receivers are saturated again.

0= -10dBm
1= -6dBm
2= -4dBM
3= -2dBm
4= 0dBm

so with these 802.15.4 series I, lowest would be -10dBm, yes?

good to know, thx

[Ioannis]

Yes, that's right
