Config MTU problem on NCS v1.6.0

[Nhuan]

Hi,

I got an issue when setting these configurations on the new NCS v1.6.0:

CONFIG_BT_L2CAP_TX_MTU=128
CONFIG_BT_L2CAP_RX_MTU=128

It has worked well on v1.5.1.

Thank you,

Nhuan

Hi!

The second config, BT_L2CAP_RX_MTU, has been removed in NCS v1.6.0 with this commit.

The new configuration is BT_BUF_ACL_RX_SIZE, which is just BT_L2CAP_RX_MTU plus the L2CAP PDU header size of 4 bytes. 

Best regards,

Heidi

Thank you very much, it worked for me.

Hi Heidi,

Thank you for this info, I was struggling with the same issue.

I have one question though. Whenever there is an update like this, where can I find details about changes that will break our code? I have been looking at release notes and such, but I could not find anything about this there by searching the config parameters that no longer work.

Best regards,

Rafael
