CC3200: Disconnection Error 109 / 110

Part Number: CC3200
Other Parts Discussed in Thread: CC3220MOD

Greetings,

I am Using C3200 MCU and I have been encountering a sudden disconnection issue which happens for no apparent reason ( resulting in my inability to reproduce it ). While debugging my code, I discovered that it's due to error 109, which is SL_WLAN_DISCONNECT_ROAMING_TRIGGER_BSS_LOSS. Therefore, I am asking for your help regarding the whereabouts of this bug ( its possible reasons, ways to solve it.. )

Thanks in advance!

UPDATE: After I tried putting the router away from my devic Containing the CC3200 MCU ( about 10 meters ), the disconnections became much more frequent ( 80 disconnections/reconnections in 20 minutes ) and the disconnection error became 110 ( SL_WLAN_DISCONNECT_ROAMING_TRIGGER_BSS_LOSS_DUE_TO_MAX_TX_RETRY ).

Dear Sir,

Thank you for answering my question.

In fact, before I attempted to post on the forum, I have read many posts ( including the two you mentionned in your comment ), still I don't really think that's the case for me because signal loss seems very unlikely to happen in my case ( device is almost adjacent to the router and everything

on the network workss fine ).

Is there any other possible causes for error 109?

Thank you in Advance.

Hi,

Do you use own hardware with CC3220 QFN chip or CC3220MOD?
How looks your RF design? Was your RF design (antenna, RF layout) validated with radio tools and equipment like a spectrum analyser?
How looks RSSI from CC3220 device and AP side?
Was your center frequency properly tuned?
Can you test with another AP?
