We have a design based on the AM3715 and WL1271 module. We have found that the scan results returned from the wl1271 do not always contain strong access points (APs) in the list.
Sometimes, the strong AP will be missing from scan results for over 5 minutes.
This appears to be happening in any environment we've tested. We do see the problem get worse in systems where a single device is serving up multiple APs.
We have seen reports of similar wl1271 issues on e2e. One report stated that the module may be not waiting long enough an a channel to see all the APs. Given this, we've tried to adjust 'max dwell time' in the wl1271 driver. We have shown that we can adjust the dwell time, but even a 1 second dwell time doesn't appear to correct the problem.
Is there anything we can do to improve our situation?
Thanks in advance...
