Perform automatic collision resolution and switch on the NFC Reader field.

Perform automatic collision resolution and switch the field on if no collision was detected. If thresholds are set to ST25R3911B_NO_THRESHOLD_ANTICOLLISION, then RF Collision Avoidance will not be performed.

Parameters

[in]	collision_threshold	Collision resolution threshold in mV peek-to-peek.
[in]	peer_threshold	Peer detection threshold in mV peek-to-peek.
[in]	delay	Delay after field on in milliseconds, according to NFC Forum Digital 2.0 Guard Time.

Return values

0	If the operation was successful. Otherwise, a (negative) error code is returned.
