'Access Point as Data Hub' example not working at data rate below 250kBaud

Other Parts Discussed in Thread: SIMPLICITI

Hi,

I've trouble running the 'Access Point as Data Hub' simpliciti 1.1.1 example when default RF configurations are modified.

Default config uses 250kBaud as data rate. Any value below 250kBaud causes the AP not recognize join packet from ED.

So AP starts to change channel as stated by frequence agility policy.

I tried to switch devices: EMCC430F6137, CC1111 usb dongle, third party ones. But with no results.

Same RF configurations works fine in the 'Simple Peer-to-Peer' example context.

I can't figure why this is happening.

Anyone experienced same problem?

thanks in advance

Hello.

Please see the Note in Section 3.4.1 of the "SimpliciTI Sample Application User's Guide."

Hope this helps.

I missed that note.

In effect disabling frequency agility solves the problem. Any RF configuration works.

It's matter to rework frequency agility algorithm if needed.

Thank you very much.

Did you ever get around to reworking the frequency agility at low data rates ex.

1.2Kbaud

5.2KHz Deviation

868MHz

54KHz Rx Filter
