BLE+2.4G proprietary based on timeslot

[iamrik]

Hello, I am working on development to concurrent multiprotocol: BLE+2.4G proprietary. I am using timeslot feature in S132. Because in my own 2.4g proprietary protocol, the settings of 2.4G module are different from BLE settings, for example, the size of S0, S1, Lenght is 0, and static length of payload is set to 128. I think it needs to set the 2.4G registers at the beginning of each timeslot and restore BLE settings at the end of each timeslot. According to example ble_app_gzll in SDK, softdevice stops when it switches to gzll, but in my application, softdevice can't stop because I need timeslot feature run always. Can you kindly to provide a solution that how can I stop BLE but not softdevice to run my own 2.4G proprietary, and come back to BLE at the end of timeslot? Regards, Rik

Hi,

The SoftDevice doesn't stop running when a timeslot is active, it is just "paused". The timeslots are placed in between radio events. If you need to set the radio registers that is no problem, they will revert to the original settings when the SoftDevice resumes its activity.

See the tutorial on timeslots, and the example on concurrent BLE and µESB in timeslots.

Best regards,
