Hello,
We developed a device using SPBTLE-1S that sends and receives data (like SPP) to an Android application (on a mobile phone), based on the BLE_Chat firmware example.
We would also like to include one more device on the above configuration, can the SPBTLE-1S serve a second connection on the same time?
I am attaching a picture to clear what i mean:

Hi SProg,
Yes, SPBTLE-1S (BlueNRG-1) can serve a second connection at the same time.
Sample project and scripts are available in DK 3.1.0 and BlueNRG GUI 3.1.0:
Please also reference documents:
C:\Program Files (x86)\STMicroelectronics\BlueNRG-1_2 DK 3.1.0\Docs\Multiple_Connection_Formula\Multiple_Connections_Formula.html

Thank you.
Kind remind that this query is supposed to be posted in Low Power RF Solutions instead, because it is not related to BLE Mesh.
