Hi Steffen, >> then the BPA500 software says: >> "100% Payload/CRC Errors" >> and it can't go after "start_encrypt_req" (that's the last Opcode in the >> Link Management Protocol). I am using BPA500 to sniff the LE data, I have seen few times below problem, the devices which you are sniffing have to be very close to the BPA500 to work well! Thanks, Vijay -----Original Message----- From: linux-bluetooth-owner@xxxxxxxxxxxxxxx [mailto:linux-bluetooth-owner@xxxxxxxxxxxxxxx] On Behalf Of Steffen Becker Sent: Thursday, March 15, 2012 2:30 PM Cc: linux-bluetooth@xxxxxxxxxxxxxxx Subject: Re: Encrypting problem while sending data via bluetooth Thank you very much, this helped me! Now everything looks fine on the screen of the "PC2". But now i got another problem regarding to this: I use a third PC with the "BPA500" (it's for bluetooth sniffing). When i use again the command PC1: # echo "test" > /dev/rfcomm0 then the BPA500 software says: "100% Payload/CRC Errors" and it can't go after "start_encrypt_req" (that's the last Opcode in the Link Management Protocol). That's why i still think i have an encryption problem. But the manpage only shows me how to ENable the encryption. So i hope somebody can help me a second time.
