AT commands

NP (Maximum Packet Payload Bytes)

Reads the maximum number of RF payload bytes that you can send in a transmission.
Using APS encryption (API transmit option bit enabled), reduces the maximum payload size by 9 bytes.
Using source routing (AR < 0xFF), further reduces the maximum payload size.
Note NP returns a hexadecimal value. For example, if NP returns 0x54, this is equivalent to 84 bytes.
