Hi, I have two USB sticks manufactured by CSR. They are class 1 EDR with LMP version 2.0. When I tried to use l2ping command, I get the following output: Ping: xx:xx:xx:xx:xx from xx:xx:xx:xx:xx:xx (data size 44) ... no response from xx:xx:xx:xx:xx:xx id 0 no response from xx:xx:xx:xx:xx:xx id 1 no response from xx:xx:xx:xx:xx:xx id 2 Recv failed: Connection timed out hci0: Type: USB BD Address: xx:xx:xx:xx:xx:xx ACL MTU: 384:8 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:1857 acl:20 sco:0 events:71 errors:0 TX bytes:1077 acl:25 sco:0 commands:30 errors:0 hci1: Type: USB BD Address: xx:xx:xx:xx:xx:xx ACL MTU: 384:8 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:717 acl:8 sco:0 events:44 errors:0 TX bytes:507 acl:8 sco:0 commands:23 errors:0 It works fine for class 2 devices. Are class 1 devices with EDR supported by Bluez as hcidump shows that they are unable to connect to each other . thanks sohel --------------------------------- Fussy? Opinionated?
