can we able to connect the nrf51422 Bluetooth other Bluetooth

[sharmelaraju]

Hi,

I am using NRF51422 in our project .We thought of using SDK 12.3 and softdevice  S130. This nrf51422 Bluetooth act as a central and this Bluetooth should connect to other controller Bluetooth which contains 1 Service base uuid which is of 128 bit and 4 characteristics which contains 128 bit Base UUID all the base  UUID are completely different  .Here  my question is can we able to connect to other device by using this nrf51422 and by using with this sdk 12.3 by adding all characterstics of 128 bit uuid and service base uuid

Hi,

This should be OK, since the S130 SoftDevice can support up to eight connections in the central role (see SoftDevice Specification):

An Initiator can only be started if there are less than eight connections established as a Central. Similarly, a connectable Advertiser can only be started if there are no connections as a Peripheral established. If there is a total of eight connections running, an Advertiser or Broadcaster cannot run simultaneously with a Scanner or Observer.

You can refer to the BLE Relay Example in the SDK.

hi .....Einar thorsurd ..

i have doubt , is it possible to connect with different uuid of peripherals using ble_app_uart_c example . i want to send the data for the particular device at the particular timing 

please help me out

Hi,

The GATT table is the same for all connections, so the same UUID's will be available for all connections. You can have a mechanism for just using separate UUID's even though all are there, but I do not see a good reason for it. This is because the GATT database data is separate for each link, even though the configuration of the table is the same. So you can use the same UUID for separate links, and they will still be independent.
