S2-LP:How to reliably abort RX while in transition through LOCK state
In my channel hopping application the radio is configured to start RX following any frequency change. However the frequency change may be followed by a TX instead so I may need to abort the RX soon after issuing CMD_RX from READY. Table 50 gives the response time for READY -> LOCK_RX -> RX as 111 us.
AFAIK, depending on whether the radio is in LOCK_RX or RX, CMD_READY or CMD_SABORT is required to transition the radio back to READY in preparation for CMD_TX. There is a potential race condition here between querying the current state which could return LOCK and issuing CMD_READY instead of CMD_SABORT. This leads to the radio not accepting the CMD_READY from the RX state and CMD_TX later also failing.
Is there a reliable way to abort the RX without looping to get the current state?
What states can be reported in MC_STATE0 during the state transition from READY to RX?
