+
+**HCI Packet Logs**
+For all Bluetooth issues, please provide a full packet log that includes initial pairing. You need to zip the packet log as GitHub does not know how to handle .pklg files. 
+
+How to get packet log depends on the port:
+- For desktop ports, full packet logging is enabled by default and the packet log is available as `/tmp/hci_dump.pklg` (Mac/Linux), or `hci_dump.pklg' (Windows).
+- For embedded ports, you can enable #define LOG_INFO in btstack_config.h and uncomment the call to 'hci_dump_open(..)' in the main() function to enable logging over UART Console or Segger RTT. Please capture text output and process using `btstack/tool/create_packet_log.py`. The tool will generate the text file into a .pklg file which can be analysed with Wireshark or Apple's PacketLogger tool.
+- For ESP32: BTstack's `port/esp32/integrate.py` script copies the current version of BTstack into the esp-idf folder. To enable packet logging, you need to edit esp-idf/components/btstack/main.c
+
+**Environment:  (please complete the following information):**
+ - Current BTstack branch: [e.g. develop]
+ - Bluetooth Controller [e.g. CSR 8510, TI CC2564C, ...]
+ - Remote device: [e.g. iPhone X with iOS 13.3]
