The datasheet is wrong for the pn532_i2c. After having constant issues with the device failing to respond on the bus and after contacting NXP about this, it turns out 1.3 ms is too tight. The official timing spec is unknown for now, but we tested 4 and 5 ms without problems. Thus we have choosen 5 ms as a safe delay. Signed-off-by: Olliver Schinagl <[email protected]>
