Communicating between the dash cam and the central server is a challenge. We are trying to send a web get request from Notehub to our AWS public http endpoint. We are able to get expected json response using manual curl as well as copying the link into web browser. However, when we set up the route in Notehub and get it this way, we always receive {‘result’: 503, ‘body’: {‘err’: ‘hub request error: response from web service does not appear to be JSON {not-json}’}}, and central server also doesn’t receive any GET requests. We tried setting up another public api route, which we are able to web get with Notehub, indicating that the route setting should work. We are adding more logging on the central server side, posted the issue on Blues forum, and contacting other teams also using Blues.
Changes
Blues Notecard doesn’t support running cellular and GPS at the same time. If one is in continuous mode, the other one needs to be in periodic mode with at least 5 minute interval. Since 5 minute interval is rather long, we are planning to purchase an additional GPS module. In the mean time, we will use the GPS location obtained by cellular data for geolocation tagging.
