9.2.2. Exiting Listen Mode
In the SX1231 V2a, the following procedure was requested to exit Listen mode:
Listen mode can simply be exited on the SX1231 V2b by resetting bit ListenOn to 0 in RegListen.
9.3. OOK Floor Threshold Default Setting
The following default value modification was required on the V2a silicon:
It is not required to modify this register any more on the SX1231 V2b.
9.4. OCP Block
The Over Current Protection block is enabled at Reset state with 95mA of current limit on the V2b silicon.
It is disabled at Reset state with 100mA of current limit on silicon V2a.
9.5. AFC Control
The following differences are observed between silicon revisions V2a and V2b:
9.5.1. AfcAutoClearOn
On the SX1231 V2a, it is required to manually clear AfcValue in RegAfcFei, when the device is in Rx mode.
AfcAutoClear function is fully functional on the silicon version V2b.
9.5.2. LowBetaAfcOn and LowBetaAfcOffset
Those two bits enable a functionality that was not available on the silicon version V2a.
