Re: L2CAP errors on linux while running 6loble


Vakul Garg <vakul.garg@...>
 

I want to add that sometimes, on zephyr console, I get:

 

[bt] [ERR] l2cap_chan_le_recv_sdu: SDU length mismatch

 

Is my application sending too big messages?

Apart from UDP, I also have a TCP connection using 6loble link.

Hi

 

I am transferring UDP packets over 6loble link between a zephyr endpoint and linux box.

On my linux box, I see errors:

 

[root@lti ~]# dmesg

[416975.584892] Bluetooth: Too much LE L2CAP data received

[416976.365482] Bluetooth: Too much LE L2CAP data received

[416977.171158] Bluetooth: Frame is too long (len 186, expected len 68)

[416977.566971] Bluetooth: Too much LE L2CAP data received

 

Can someone please provide some hint what could I be doing wrong?

I am using linux kernel version 4.13.12.

 

Regards
