CC2640: Establishing connection without BLE Stack

Hello,

First of all, I'm developing firmware on a CC2640 without the BLE Stack. I'm trying to optimize the amount of time that the radio is active during a connection. To achieve this I'm trying to use the triggers defined in slave command parameters which are timeout trigger and end trigger(Table 23.89 in Technical Reference Manual).

As stated in 23.6.4.2 Slave Command section of Technical Reference Manual "The parameters pParams->timeoutTrigger and pParams->timeoutTime define the time to end the operation if no sync is found by the demodulator. The startTrigger and pParams->timeoutTrigger together define the receive window for the slave.", I'm using start trigger as TRIG_NOW and I'm trying different triggers to end this reception at a specific amount of time which is the window size for BLE.

I have tried both absolute timing(TRIG_ABSTIME) and relative timing(TRIG_REL_SUBMIT) for the radio to end the slave command but it always stays active with relative timing and doesn't stop at the time that I write to timeout time for absolute timing. I thought the problem might be because I was not using CMD_SYNC_START_RAT command for radio timer. But I also fixed that buy using CMD_START_RAT for the first time after system boot and CMD_SYNC_START_RAT with rat0 value received from CMD_SYNC_STOP_RAT command. Fixing it didn't solve the timeout issue either.

I would very much appreciate it, if someone can help me with this timeout trigger timing by giving an example such as what should I write to timeout time and end time parameters for the slave command for example given 10 ms of window size.

Thank you very much in advance.
