| 2 | Panasonic PAN1321 Bluetooth module | |
| 3 | ------------------------------------------------------------------------------- | |
| 4 | ||
| 5 | This is an example capture of the serial (UART) init for the Panasonic | |
| 6 | PAN1321 Bluetooth module. | |
| 7 | ||
| 8 | The firmware sends the init commands at 115200 baud, with 8n1 settings. | |

| 16 | Logic analyzer setup | |
| 17 | -------------------- | |
| 18 | ||
| 19 | The logic analyzer used for capturing is a ChronoVu LA8 at a sample rate | |
| 20 | of 500kHz. | |
| 21 | ||
| 22 | The logic analyzer probes were connected like this: | |
| 23 | ||
| 24 | Probe PAN1321 | |
| 25 | ------------------- | |
| 26 | 0 (green) TX | |
| 27 | 1 (orange) RX | |
| 28 | GND GND | |
| 29 | ||
| 30 | ||
| 31 | Successful initialization | |
| 32 | ------------------------- | |
| 33 | ||
| 34 | The sigrok command line used was: | |
| 35 | ||
| 36 | sigrok-cli -d 0:samplerate=500khz --samples 8388608 \ | |
| 37 | -p '1=TX,2=RX' -o panasonic_pan1321_init.sr | |
| 38 | ||
| 39 | The data sent (S) to the PAN1321 module and received from it (R) was: | |
| 40 | ||
| 41 | R: ROK\r\n | |
| 42 | S: AT+JSEC=1,1,2,04,7777\r\n | |
| 43 | R: OK\r\n | |
| 44 | S: AT+JDIS=3\r\n | |
| 45 | R: OK\r\n | |
| 46 | S: AT+JRLS=1101,11,Serial port,01,000000\r\n | |
| 47 | R: OK\r\n | |
| 48 | S: AT+JSLN=21,MyCoolBluetoothDevice\r\n | |
| 49 | R: OK\r\n | |
| 50 | S: AT+JAAC=1\r\n | |
| 51 | R: OK\r\n | |
| 52 | S: AT+JSCR\r\n | |
| 53 | R: OK\r\n | |
| 54 | ||
| 55 | ||
| 56 | Successful initialization, triggered | |
| 57 | ------------------------------------ | |
| 58 | ||
| 59 | The sigrok command line used was: | |
| 60 | ||
| 61 | sigrok-cli -d 0:samplerate=500khz --samples 8388608 \ | |
| 62 | -p '1=TX,2=RX' --wait-trigger --triggers 2=1 \ | |
| 63 | -o panasonic_pan1321_init_triggered.sr | |
| 64 | ||
| 65 | The data sent/received is the same as in the above example. The difference | |
| 66 | is that we triggered on the first high RX state, which might lead to | |
| 67 | some garbage for the first few decoded characters. This is file intended as | |
| 68 | a test-case for this situation. | |
| 69 | ||
| 70 | ||
| 71 | Invalid command, error code | |
| 72 | --------------------------- | |
| 73 | ||
| 74 | The sigrok command line used was: | |
| 75 | ||
| 76 | sigrok-cli -d 0:samplerate=500khz --samples 8388608 \ | |
| 77 | -p '1=TX,2=RX' -o panasonic_pan1321_error.sr | |
| 78 | ||
| 79 | R: ROK\r\n | |
| 80 | S: AT+JSEC=1,1,2,04,7777\r\n | |
| 81 | R: OK\r\n | |
| 82 | S: AT+JDIS=9\r\n | |
| 83 | R: ERR=-1\r\n | |
| 84 | ||
| 85 | As 9 is an invalid value for the "AT+JDIS=" command, the device returns | |
| 86 | an error code. | |
