Hi,

I want to read data from a sensor device over BLE by different clients (smartphones) at the same time. Can this be done with the protocolstack? And if so, are there examples available or is anyone willing to share their code?

Looking forward to your reply,

Kris

Kris,

  PSoC 4 BLE devices supports only one connection at a time , so you can not connect multiple devices simultaneously over BLE.  But there are some approaches you may implement like - Instead of simultaneously , you can connect in time multiplexed fashion , or without establishing a BLE connection you may communicate through Broadcast packets etc ....Also our PSoC 6 BLE device supports 4 connection simultaneously and you may go for it.

For PSoC 4 BLE various code examples , please refer below link --
