In our product we are using Stonestreetone Bluetooth stack v4.0.5 with module PAN1326
We found strange issue in communicating with Nexus5 phone. After truing to set sniff mode in FW connection freezes and drops after few seconds. HCI log from phone in attachment,
In our firmware we observed Sniff_Subrating_Event:
[DBG_BT] HCI evt: Sniff_Subrating_Event
[DBG_BT] Status: 0
[DBG_BT] Connection_Handle: 1
[DBG_BT] Maximum_Transmit_Latency: 90
[DBG_BT] Maximum_Receive_Latency: 1170
[DBG_BT] Minimum_Remote_Timeout: 0
[DBG_BT] Minimum_Local_Timeout: 2
Other phones have no such issues. Nexus5 was tested with Android4.4 and Android5 and result the same.
