If operating in API mode and using escaped characters (AP=2), is the maximum payload size reduced? In other words, if my un-escaped message fills the maximum payload (ATNP = 84), but after applying the escaping it exceeds this number, must I reduce the message size to take into account the added escape characters (0x7D)? In the worst case, if my data was 84 bytes of '0x11' then I could I send 168 bytes total (0x7D, 0x31, 0x7D, 0x31,.....) or do I have to send only 42 bytes?
