These results where metered with software version 1.2.97 while continuously scanning wifi and ble, no LoRa TX’ing, OLED display (if present) on, 5V USB powered.
<b>Power consumption</b> was metered at around 1000mW, depending on board (i.e. has display or not) and user settings in paxcounter.conf. If you are limited on battery, you may want to save around 30% power by disabling bluetooth (commenting out line *#define BLECOUNTER* in paxcounter.conf).

# Uploading
To upload the code to your ESP32 board this needs to be switched from run to bootloader mode. Boards with USB bridge like Heltec and TTGO usually have an onboard logic which allows soft switching by the upload tool. In PlatformIO this happenes automatically.<p>
The LoPy/LoPy4 board needs to be set manually. See these

The original Pycom firmware is not needed, so there is no need to update it before flashing Paxcounter. Just flash the compiled paxcounter binary (.elf file) on your LoPy/LoPy4. If you later want to go back to the Pycom firmware, download the firmware from Pycom and flash it over.

Paxcounter generates identifiers for sniffed MAC adresses and collects them temporary in the device's RAM for a configurable scan cycle time (default 240 seconds). After each scan cycle the collected identifiers are cleared. Identifiers are generated by salting and hashing MAC adresses. The random salt value changes after each scan cycle. Identifiers and MAC adresses are never transferred to the LoRaWAN network. No persistent storing of MAC adresses, identifiers or timestamps and no other kind of analytics than counting are implemented in this code. Wireless networks are not touched by this code, but MAC adresses from wireless devices as well within as not within wireless networks, regardless if encrypted or unencrypted, are sniffed and processed by this code. If the bluetooth option in the code is enabled, bluetooth MACs are scanned and processed by the included BLE stack, then hashed and counted by this code.

If you're using [TheThingsNetwork](https://www.thethingsnetwork.org/) (TTN) you may want to use a payload converter. Go to TTN Console - Application - Payload Formats and paste the code example below in tabs Decoder and Converter. Make sure that your application parses the fields `pax`, `ble` and `wifi`.
To map a GPS capable paxcounter device and at the same time contribute to TTN coverage mapping, you simply activate the [TTNmapper integration](https://www.thethingsnetwork.org/docs/applications/ttnmapper/) in TTN Console. Paxcounter generates ttnmapper compatible data fields.
**Decoder:**
```javascript
function Decoder(bytes, port) {
var decoded = {};
if (port === 1) {
var i = 0;
decoded.wifi = (bytes[i++] << 8) | bytes[i++];
decoded.ble = (bytes[i++] << 8) | bytes[i++];
if (bytes.length > 4) {
decoded.latitude = ( (bytes[i++]) | (bytes[i++] << 8) | (bytes[i++] << 16) | bytes[i++] << 24 );
decoded.longitude = ( (bytes[i++]) | (bytes[i++] << 8) | (bytes[i++] << 16) | bytes[i++] << 24 );
decoded.sats = ( bytes[i++] | (bytes[i++] << 8) );
decoded.hdop = ( bytes[i++] | (bytes[i++] << 8) );
decoded.altitude = ( bytes[i++] | (bytes[i++] << 8) );
}
}
return decoded;
}
```
**Converter:**
```javascript
function Converter(decoded, port) {
var converted = decoded;
if (port === 1) {
converted.pax = converted.ble + converted.wifi;
if (converted.hdop) {
converted.hdop /= 100;
converted.latitude /= 1000000;
converted.longitude /= 1000000;
}
}
return converted;

* Scan duration sets how long scanning should be going on, interrupting a wifi scan cycle.
* Scan window sets how much of the interval should be occupied by scanning.
* Scan duration sets how long scanning should be going on, before starting a new scan cycle. 0 means infinite (default).
* Scan window sets how much of the interval should be occupied by scanning. Should be >= BLESCANINTERVAL.
* Scan interval is how long scanning should be done on each channel. BLE uses 3 channels for advertising.
* -> Adjust these values with power consumption in mind if power is limited.
* -> Scan interval can be changed during runtime by remote comammand.
