NRF52832 as BLE central and max allowed connections?

I have configured BLE module which has an NRF52832 SOC to behave as a BLE central or rather it scans for advertisement packets. Currently it connects to one device and even though I have not explicitly called the stopScan API, no further advertisement packets are received by the BLE central, even though I have two BLE peripheral devices transmitting their respective advertisement packets.

At any given time only one of them gets connected. I had read some documentation on the Nordic site, that central can connect upto 8 peripheral devices? If so am I missing something in the scan API on the BLE central? Any guidance in this matter is greatly appreciated?

Thanks, Ajay.

The nRF52 Development Kit is a single-board development kit for Bluetooth Smart, ANT and 2.4GHz proprietary applications using the nRF52 Series SoC. This kit supports both development for nRF52832 SoCs.

After eatch connection, the scanning is immediately off - you need to turn it on again. For current implementation you should been able to connect up to 3 peripherial devices.

Thanks a lot for you response as always Andrzej. Is this an mbed BLE implementation limitation of the number of devices that can connect on NRF52832 or is it something of a Nordic restriction on BLE central devices based on NRF52832?

Thanks, Ajay
