I am trying out bluez on linux with CC2540 - I tried out hciattach since after I plugged in the device, it enumerated a serial device & got -
$ sudo hciattach /dev/ttyACM0 texas 57600
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/TIInit_0.2.16.bts
Loaded BTS script version 1
TI init command failed.
Can't initialize device: Input/output error
Is this the right way to enable BlueZ on CC2540 dongle ? Where can I find - TIInit_0.2.16.bts ?
