Hi Jimmy,

I was able to solve the problem thanks to you 🙂.

Thanks a million again.

Hi,

you can use the device name as the scanning filter for the connection.

for example, I did the example on the peripheral and central role (both device)

github.com/.../main.c

static char const m_target_periph_name[] = "Peripheral_PER";

for the SDK 15.3, it has the scan module to easy configure.
