How do I disable transparent data mode in EZ-Serial for the Vela IF820?

Transparent data mode can be disabled with bit 1 of the SPPM command as below. This can be used in both text and binary parse modes

(<<) SPPM,M=2

(>>) @R,000A,SPPM,0000

Now when entering a SPP connection instead of going straight into transparent data mode EZ-Serial will remain in command mode and allow the use of commands such as 

Query Connections

(<<) /btqc

(>>) @R,0010,/BTQC,0000,C=01

(>>) @E,002D,BTCS,C=01,A=0016A4001589,T=01,B=00,R=00,S=00

Query peer address

(<<) /btqpa,c=1

(>>) @R,0020,/BTQPA,0000,A=0016A4001589,T=00

Query RSSI

(<<) /btqss,a=58a0238ed80b

(>>) @R,0011,/BTQSS,0502,R=00

You can also send a disconnect command

(<<) /btdis,c=1

(>>) @R,000C,/BTDIS,0000

(>>) @E,0012,BTDIS,C=01,R=0000

To send data in this mode use

(<<) .spps,c=1,d=4C6169726420436F6E6E6563746976697479 

(>>) @R,0010,.SPPS,0000,C=01

Where c = the connection handle and d = is the outgoing payload in hex

When receiving data in this mode you will see

(>>) @E,0016,.SPPD,C=01,D=4D61726B

where c is the connection handle and d is the incoming data in hex
