Hopeful that I will someday get even one of the WiShield sketches to compile without errors for my brand new WiShield, I have begun looking to the future and the WiServer.pde example sketch.

The WEP key is evidently entered into the area of the sketch as shown below:

Code: Select all

// WEP 128-bit keys
// sample HEX keys
prog_uchar wep_keys[] PROGMEM = { (bunch of HEX digits separated by commas here)

However, my wireless environment is WEP encoded to 64-bits, thus only a 10-digit HEX string is required for Key 0. Can I simply plug my 10 HEX characters into the progmem space and hope that WiShield will somehow figure out how to log onto the network?

Yes, it does support 64-bit WEP.

You will have to put your key into the array in the sketch and zero out all the unused bytes,

Code: Select all

// WEP 64-bit keys
// sample HEX keys
prog_uchar wep_keys[] PROGMEM = {
              0x01,0x02,0x03,0x04,0x05,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, // Key 0
              0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, // Key 1
              0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, // Key 2
              0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00  // Key 3
            };


Also, change keyLen from 13 to 5 in the following function in g2100.c,

Code: Select all

void zg_write_wep_key(U8* cmd_buf)
{
   zg_wep_key_req_t* cmd = (zg_wep_key_req_t*)cmd_buf;

   cmd->slot = 3;      // WEP key slot
   cmd->keyLen = 5;   // Key length: 5 bytes (64-bit WEP); 13 bytes (128-bit WEP)
   cmd->defID = 0;      // Default key ID: Key 0, 1, 2, 3
   cmd->ssidLen = ssid_len;
   memset(cmd->ssid, 0x00, 32);
   memcpy_P(cmd->ssid, ssid, ssid_len);
   memcpy_P(cmd->key, wep_keys, ZG_MAX_ENCRYPTION_KEYS * ZG_MAX_ENCRYPTION_KEY_SIZE);

   return;
}

Thanks for the tip, Benquark.

The change was made, and I deleted the corresponding .o file.

Nice to have your expert help while I try to bring this thing up.

OK, one last (I hope) question. Looks like there are only 5 hex numbers to enter. But my key is 9709462240. Does that mean I only put in the first 5 digits? i.e. 0x39,0x37,0x30,0x39,0x34, and the rest of the digits are 0x00. Is this true?

Thanks so very much!!!

I think you will want to enter in all ten - two per hex digit.

9709462240 becomes 0x97, 0x09, 0x46, 0x22, 0x40

Let us know if it works!

It worked for me.

Many thanks.
