NCS NUS buffer size

[Michel]

I'm using the peripheral_uart example and I'm trying to increase the buffer size.

At this point the buffer size is 20 although I changed in my prj.conf the following:

CONFIG_BT_GATT_NUS_UART_BUFFER_SIZE=128
CONFIG_BT_RX_BUF_LEN=128
CONFIG_BT_L2CAP_TX_MTU=128
CONFIG_BT_L2CAP_RX_MTU=128

What am I doing wrong?

Thank you for the reply. The last topic was very helpfull.

However the biggest mistake was my code self. I print my data to a string with length 20. So only the 20 first characters would be send.
