WL18XX-BT-SP: Bluetooth TX RX BER meter test data analysis

Part Number: WL18XX-BT-SP
Other Parts Discussed in Thread: WL1835MOD, WL1835

Hello,

We're interested in analyzing the Bluetooth BER test transmission data on the Wl1835MOD. To do this, we've utilized two WL1835MOD devices, one designated as the TX and the other as the RX.

Please see the commands below for enabling the TX and RX BER test in Bluetopia PM SS1 tool format:

**TX End:**

```
SS1Tool cmd 0x3f 0x006 0x34 0x12 0x78 0x56 0x34 0x12
SS1Tool cmd 0x3f 0x1CC 0x01 0x03 0x62 0x09 0xff 0xff 0x05 0x00 0x1b 0x00 0x07 0x01 0xff 0x01
```

**RX End:**

```
SS1Tool cmd 0x3f 0x01fb 0x01 0xff 0x00 0x00 0x00 0x00 0x01
SS1Tool cmd 0x3f 0x01cb 0x62 0x09 0x01 0x01
SS1Tool cmd 0x3f 0x18B 0x00 0x00 0x34 0x12 0x78 0x56 0x34 0x12 0x01 0x01 0x1B 0x00 0xE8 0x03 0xFF 0x01 0x01
Delay 5000 (ms)
SS1Tool cmd 0x3f 0x113
```

We anticipate results from this setup. However, we encountered an issue as we couldn't verify the TX data in the nRF sniffer tool. Could you please provide guidance on how to verify the TX data in the nRF sniffer?

Based on the sniffer data, we're considering replacing the WL1835 TX with a signal generator. Could you also specify the signal generator used for this test?

I've attached the sniffer capture for your reference.

Thank you,
Bala
