I am confused about the ADRACKReq bit on Figure 14

The following is a figure (figure 14) of LoRaWAN Specification V 1.1 which is made by LoRa Alliance :

According to the LoRaWAN Specification V 1.1, When the ADR_ACK_CNT >= ADR_ACK_LIMIT, the device will set the ADRACKReq bit. In Figure 14 , the ADR_ACK_LIMIT and ADR_ACK_DELAY constants are both equal to 32. So when the ADR_ACK_CNT >=32, the ADRACKReq bit should be set. But in Figure 14, even when the ADR_ACK_CNT = 63, the ADRACKReq bit is still not set. Why?

For me it’s look like an error in the sentence “assuming ADR_ACK_LIMIT and ADR_ACK_DELAY constants are both equal to 32.”

The table look like they assume that ADR_ACK_LIMIT = 64 and ADR_ACK_DELAY = 32, which are the recommended values for all the region in “LoRaWAN 1.1 Regional Parameters”

I think so, but the lorawan specification is a standard and there is nearly impossible a mistake. So I asked your guys to confirmed about that.

Hi, Guys:
Is there anyone know about that?
