Connecting EB500 to BS2SX stamp without Board of Education

We've tried connecting a eb500 to a bs2sx stamp without the use of board of education.
Our connections from EB500 to BS2sx are as follow:
Pin 1 (VSS) and Pin 20(VCC) connected to a power supply
Pin 3 (TX) to P0
Pin 4 (RX) to P1
Pin 8 (status) to P0
Pin 9 (mode) to P1
We tried using the code to Get the eb500 Address:
'{$STAMP BS2}
szData VAR BYTE(20)
'Wait for the eb500 radio to be ready
PAUSE 1000
'Get the eb500 Bluetooth Address
SEROUT 1,84,[noparse][[/noparse]"get addr",CR]
SERIN 0,84,[noparse][[/noparse]WAIT(“ACK”,CR)]
'Read the local address from the get command
SERIN 0,84,[noparse][[/noparse]STR szData\17]
SERIN 0,84,[noparse]/noparse]WAIT(CR,”>”[noparse];)[/noparse
szData(17) = 0
DEBUG STR szData\17,CR
however we got no output address on the debug terminal.
Is there any way to check if the·eb500 is working?
Are there any links of schematics for connections between the bs2sx stamp and the eb500 without the use of BOE or any other boards?
-Thanks in advance.

Parallax Inc. cannot support the use of the EB500 in a manner not consistent with its design (used on a BOE). That said, the documentation from A7 Engineering does provide the pin out of the device, though I have found that many customers need to review both the manual and the specifications sheet to grasp the correct pin out. Of course, you can get the pin out of the AppMod socket on the BOE by reading the silkscreen on the PCB. I hope this helps. Take care.
