Multilink peripheral RAM settings

[Martin Kulessa]

Hi, i try to establish a communication between 3 sensors in the following way!

Node 1 should broadcast messages to Node 2 and Node 3 as Peripheral. To establish a connection now between Node 1 and Node 2, Node 2 acts as central and connects to Node 3 as a seconde peripheral device!

First of all is it possible to use the Multiperipheral on nRF51422 or just on nRF52 series?

Second how do i have to extend the RAM to use a second Peripheral based on ble_nus_uart app peripheral?

The latest version of the S130 SoftDevice, for the nRF51, does not support multiperipheral, so your suggested topology is not possible.

Node 1 can be connected to Node 2 as a central, and to Node 3 as a peripheral.

Node 2 can be connected to Node 3 as a central, and to Node 1 as a peripheral.

Node 3 can be connected to Node 1 as a central, and to Node 2 as a peripheral.

1. Yes my Problem is also time dependence! Even if there are no guarantees for Bluetooth Low Energie and i could use the generic Radio is there a difference of the broadcast time to be expected when i broadcast from Node1 to a central (Node 3) or from Node 1 to a peripheral (Node2)
2. On nRF52 S132 4.0.3 how do i have to change the applications RAM settings to extend the peripherals from 1 to 2 in the ble_app_uart for example?
