S130: Simultaneous connecting to multiple peripherals

puz_md

Hi,

the S130 supports multiple connections for the Central role. Is it possible to connect to multiple devices at the same time? E.g. calling sd_ble_gap_connect() asynchronously multiple times with different peer addresses before a timeout or a connection event has occured.

My goal is to have multiple central services/profiles that handle their connections independently of each other. Is this possible? Or will I need to use some kind of connection manager that synchronizes GAP access between the services?

Also, we will have an Observer running in background. Will it be possible to keep scanning during connection establishment to peripheral devices? In the past, it seems I had to call sd_ble_gap_scan_stop() before calling sd_ble_gap_connect().

    We have device A that implements a Dual Role or rather Triple Role (Peripheral, Central and Observer). Then we have several slave devices B, C and D (maybe more in the future) running in Peripheral mode that each implement different functionality a different Bluetooth profile. At startup, device A shall connect to devices B, C and D. Also, it shall reconnect if the connection is lost and it shall connect if A, B or C becomes available only after A has already started. This is the background functionality we need. Further, there are devices X, Y, Z, also running in peripheral mode, which implement the same profile but send different advertising data. Upon a trigger event, device A scans for advertising packets and depending on the advertising data connects to one of X, Y, Z etc. This is the main functionality. But connection to the slave devices (B, C, D etc.) should be kept and (re-) established at the same time. I already have a coarse Idea about how to implement this, based on your answer.
