Hi, Nordic Team
My development environment is PCA10028, SoftDevice 130, SDK12.3.0
I use a s130_nrf51_2.0.1_softdevice.hex.
It is based on ble_app_multilink_central and experimental_ble_app_blinky.
See also devzone.nordicsemi.com/.../can-the-nrf51822-be-used-as-a-twi-slave
#define CENTRAL_LINK_COUNT 7 //8 /**< Number of central links used by the application. When changing this number remember to adjust the RAM settings*/
#define PERIPHERAL_LINK_COUNT 1 //0
Up to six peripherals can be reliably connected to the Central as shown in the attached video.
However, when the peripheral devices become seven, they are repeatedly connected and disconnected at the moment.
In the video blue is a connection Yellow is disconnection
Best regards,
Alex
