Last year I wrote about the issue, that Gateway stopped receiving messages/reports from devices. This was happening once a day and sometimes a couple of times per day.

I contacted Telink support and wrote about it on the forum but the issue was not fixed.

Probably a month ago I have decided to disable BLE scanning in advertising mode - SCAN_IN_ADV_STATE 0.

Since then, I didn t have any issues with receiving messages from ZigBee devices.

So, it looks like BLE scanning caused this issue.

Could Telink have a look why this would be the case?

Edit:

I have just downloaded latest SDK v2.3.2.1 and in the release notes there is note about the bug fix:

## V2.3.2.1
### Bugs
* buffer overflown issue under SCAN_IN_ADV_STATE mode

Does this fix this issue?
