Status: Improving

Please take a look and build our wiki page https://github.com/lamegaton/Comm-and-Sensor---Speed-e/wiki
I've changed the name to Beyond Speed-E because I wanted to improve and make this work for any sensors. new line = two space

Power

1. library we are using: https://github.com/rocketscream/Low-Power

Sensor

1. confidence level of car is around 5-7
2. our max distance is 14 feet from the curve to the first white stripe line
3. on 04/18/2019, we remove calibration code because it's not important
4. change trig time to 20s and echo to 2s

Communication

1. planning to use different spreading factor for diffrent node
2. We've trying to get the downlink from TTN from node
3. For testing and increase the range, we set the gateway to single channel and single Spreading factor (10)

Length of wire antenna for:
915 MHz : 8.2 cm

Lmic

Please use the below library
https://github.com/mcci-catena/arduino-lmic
os_setTimedCallback(&sendjob, os_getTime() + ms2osticks(10), do_send); //do a send

Schedule time to send

#define ms2osticks(ms) ((ostime_t)( ((s8_t)(ms) * OSTICKS_PER_SEC) / 1000)) // or using us2osticks
os_runloop_once(); //check status

Disable Adaptive Data Rate
LMIC_setAdrMode(false);

Location

1. Gateway:
   32.777651, -117.070372

2. Node 1:
   32°46'43.9"N 117°04'23.6"W
   32.778863, -117.073228 (end segment -- sensor position)
   32.778916, -117.074302 (start segment)

Point	location	note
1	32.778949, -117.072468	only work at this point
2	32.778953, -117.071395	the gateway recieves signal from node2 to node3
3	32.778955, -117.070642
gateway	32.777651, -117.070372

User interface

https://developers.google.com/maps/documentation/javascript/overlays?csw=1#ImageMapTypes https://docs.mapbox.com/mapbox-gl-js/api/#customlayerinterface

https://angus.readthedocs.io/en/2014/amazon/transfer-files-between-instance.html

what we want to achieve at this point is showing red segment when car <= 8 and car > 3 and showing green segment when car > 24 (look at matlab file to see our logic)

We can use this instead:
https://developer.tomtom.com/maps-sdk-web/functional-examples#map-vector-geojson
or another option: mapbox
also we need to fetch data to mapbox...

Notes for team:

1. Please write code in block or function so we can easily intergrate
2. we have only 18 days left babes!
3. If you want to upload a new code with lmic, you have to change NWKey and APPKey
