You can use&nbsp;<a href="https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Sniffer">nRF Sniffer</a> if you have a Nordic kit to spare.&nbsp;</li> </ol> <p>The GATT LMP TIMEOUT error is not an uncommon topic here on devzone. You can try to browse through <a href="https://devzone.nordicsemi.com/search?q=android%20gatt%20lmp%20timeout">some of these posts</a> and see if you find a solution.</p><div style="clear:both;"></div>
