Sending frames from Kyneo to a mobile phone
Mobile phones have small global positioning antennas that present several problems due to lack of sensitivity, signal rebound errors or inability to connect to more than one satellite constellation. This means that in some circumstances we cannot trust faithfully on the location information that it is providing. In this post, we present Kyneo as a reliable GNSS information source to support our mobile device operation.
The useful application would be to draw the positioning data directly on a map showed on our mobile screen, but what we are going to do in this project is to see what is lying beneath that process.
Connecting to Kyneo
First of all, we need to download an app that allows us to see the raw data that our phone receives via Bluetooth. Android free app «Bluetooth Terminal» has been succesfully tested for this purpose.
Now we need to link the Kyneo unit to our mobile phone via Bluetooth. Once this is done, we will be able to read the GNSS frames sent by Kyneo. Depending on the preferences set in our Kyneo code, we will receive the corresponging data frames with the corresponding periodicity (GPGLL, GPRMC, GPVTG...).
