BLE gatt client buffer size

[weizhen]

Hi,

I am working on a BLE gatt service client. I found I only can read and write in 22 bytes, I already change the buf size to what I want by using 

CONFIG_BT_L2CAP_TX_MTU=508
CONFIG_BT_BUF_ACL_TX_SIZE=512
CONFIG_BT_BUF_ACL_RX_SIZE=512

but it still not working. is that anything I need to change to make the buffer larger?

Hi!

Please see the following answer:

 Data transfer to a characteristic is limited to 20 bytes 

Best regards,
