CC2541DK-MINI: I want to connect to multiple sensor tags from CC2540 dongle - control LEDs

Part Number: CC2541DK-MINI
Other Parts Discussed in Thread: CC2541, CC2540, CC1352P, CC1352R, CC1350

Support,

I have USB dongle working with Btool and I can connect to the supplied CC2541 sensor tag but I want to connect to multiple CC1352 sensor tags (2.4GHz mode).  I want to be able to control LEDs on the sensor tags.

1. has anyone connected CC1352 to CC2540

2. has anyone controlled features on the sensor tag from the CC2540 using Btool or some other app?

Regards,

Marc

    Hi pathfinder,

    I have requested a concerned engineer to look into this issue. Please expect a reply within the next business days.

    Hi,

    The CC2541 does not support multiple connections so this is not possible.

    The other way (connecting multiple CC2541 sensors to one CC1352P BLE master or slave) is possible.

    Marie,

    Thank you for the response!  It is bad news though. 

    I'm looking for to access multiple sensor tags via a PC based app.  Is there any way to connect a CC1352(BLE) launchpad to the PC, then have it connect to multiple tags?

    Regards,

    Marc

    Hi Marc,

    Yes, the CC1352P/CC1352R devices both support multi-role. So you could have one CC1352P connected to a PC as a slave, and connecting to CC2541 sensors as the master (or vice versa).

    You can find the multi role example project here:

    Marie,

    Will the PC side application be a console presented by the CC1352P Launchpad?

    Again, a part of what I'm looking for is the ability for the PC to write/access/control the CC1352P LP to initiate communication commands to one or more of the CC2541 sensor tags (or CC1350 sensor tags).  Something as simple as 'turn on/off LED'

    Regards,

    Marc

    Hi,

    If your PC supports BLE you could probably write a service that is hosted on the CC1352P. When the PC writes to this service the application on the CC1352P would interact with the sensor tags.
