Multiple concurrent connections

[ned_zeppelin]

Hi,

I have some questions regarding connecting multiple (as many as possible) BLE peripheral devices to a single central (simultaneously).

1: Does anyone know of any device (specialized embedded device or phone, tablet, PC) that is capable of maintaining 25 simultaneous connections?

2: How many simultaneous connections (to peripherals) can a Nordic nrf51 dongle maintain (using the Master Emulator drivers or any other available API/interface)?

3: Would it be possible to have more than 1 nrf51 dongle connected to a single PC in order to expand the number of simultaneous connections?

Hi Ned,

1. I haven't experienced any device support that much of peripheral. Last time I tried, was about 6-7 peripheral max. But it was long ago.

2. You can use BLE driver (the Master Emulator only support 1) that runs on S130, now you can have 3 but later you can have up to 8 peripherals simultaneously when BLE driver use S130 v2.0. If you don't want to wait, you may need to use the serialization example in the SDK directly and make your own API to control the central via UART.

3. I think it should be OK, you are using two different COMPORT so it should be fine.

OK, thanks!
