Hello,

For our device only one SPP session will be active at a time. If you wanna do SPP transfer with second device , you need to disconnect SPP connection from the first device.

You can test our SPP snip project (/20719-B1_Bluetooth/apps/snip/bt/spp) . Pair with first device, after that pair with second device and do SPP connect to one after the other.

There are settings in wiced_bt_cfg.c for RFCOMM that suggest it may be possible to have multiple connections.  How many simultaneous RFCOMM connections are supported?

Hi ,

Yes RFCOMM multiple connections are possible depending upon the settings in wiced_bt_cfg.c file.

However currently our WICED SDK support only 1 SPP connection at a time.

Thanks,
