FONA 808 GPS Speed

Post by silverstar »

In my application, I want the FONA/Arduino combo to go as fast as possible. However, I receive data that can not be correct such as:
1 Shows speed at all times even when stopped. Stopped speed usually less than 1 mph but i have seen it sow a higher number (2 mph).
2. When stopped the course swings widely. Even when running, I receive changes in direction that do not seem to make sense.

My fear is that I am expecting too much and am possibly over driving the FONA. Some code examples I have seen seem to add a 100 ms or so delay to let the the device "settle down". Should I add a small delay after reading the device? I will change the software to slow it down a little
