Hi, I'm using bluez v5.50 on Linux 4.9 on an embedded arm board. When I use hcidump and then connect to the device over BLE I get a segfault. The log until that point is: > HCI Event: LE Meta Event (0x3e) plen 19 LE Connection Complete status 0x00 handle 128, role slave bdaddr 55:3A:69:2B:2E:98 (Random) < HCI Command: LE Read Remote Used Features (0x08|0x0016) plen 2 > HCI Event: Command Status (0x0f) plen 4 LE Read Remote Used Features (0x08|0x0016) status 0x00 ncmd 1 > ACL data: handle 128 flags 0x02 dlen 11 ATT: Handle indicate (0x1d) > HCI Event: LE Meta Event (0x3e) plen 11 Segmentation fault If I run it under valgrind I get: ==1944== Invalid read of size 1 ==1944== at 0x4842B10: strlen (in /usr/lib/valgrind/vgpreload_memcheck-arm-linux.so) ==1944== Address 0x726f is not stack'd, malloc'd or (recently) free'd Kind regards Troels Dalsgaard Hoffmeyer This e-mail is confidential and may be read, copied and used only by the intended recipient.
