Maximum performance on nrf51822 ?

[Fabien Comte]

Hello,

I work on nrf51822 with S130. I use nus service with uart_c and it's very slow (500 ms to send "abc" test string).

I am not energy limited on this application. How can i speed up ?

I have a 16 MHz quartz on my board and a 32 KHz but i use the default one (not sure the one used).

I tried to set connection times to minimum but i'm not sure if they are really used.

Connection is long too (ready after 6 to 8 seconds). Is that a normal connection time ?
