nrf51822 Custom Hardware slow connection

[Luis Alberto]

Hi guys,

I have a custom hardware with the nrf51822 and we have a slow connection and services discovery is clearly slower that when we run the code in the Development kit (PCA10004 on a nrfgo motherboard). Our custom hardware uses the internal RC because it does not have the 32KHz external crystal (NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION) We also use a wire as antena, besides that everything else seems to be the same as the PCA10004. Since the development kit works fast even with the RC enable, that makes me thing that must be something regarding the hardware, am I right?

Sorry, It was my mistake. I've check again and I did have different advertising parameter for both, connection interval were the same. Once the advertising were the same, all start working fine. Also, I didn't see any retransmissions with the sniffer. Thanks!
