BTS file TIInit_7.6.15.bts for Tiwi-BLE

Hi,
We are using TiWi-BLE with iMX6 (kernel 4.1.15). In rare case, the communication between APP (from Android devices) and Gatt services stopped and the Gatt services were no longer discoverable. However, we still can reset/restart the BLE module and make the Gatt services become discoverabe. Not a wile ago, I found a newer TIInit_7.6.15.bts file (version TI_P6_15.93 from http://processors.wiki.ti.com/index.php/Bluetooth_BTS_files_overview ) and replaced the existing one (version TI_P6_15.64 ). The symptom became worse. Packets were dropped more often and the server would crash if we tried to reset/restart the module. Before the server crashed, there were many “Bluetooth: hci0 cmd xxxx tx timeout” errors being reported. Is this right version for our platform? If yes, why the communication drop? for the details, please see the attachment. Thanks.

BTS file TIInit_7.6.15.bts for Tiwi-BLE

The correct bts file is downloadable on the TiWi-BLE product page at the below like. It has a part number parentheses, 480-0048. This is the only bts file that should be used with the TiWi-BLE. If you determine the original problem where GATT services stopped is not being cause by your application, and a driver issue is suspected, a case should be opened at ews-support@lairdtech.com.

Best Regards,

I downloaded the file you mentioned from https://www.lsr.com/embedded-wireless-modules/wifi-plus-bluetooth-module/tiwi-ble#product-software. They are the same file. I'll do more investigation to determine the cause.
