The problem is that you disconnect too quickly. Try keeping connection open or disable geocoding.
Hi,
Do you have the correct ArduinoJson.h file for me?
Hi I have a project about GPS. I am using sim800c and arduino leonardo. When I try to send data to traccar server, I can not see the datas on server. Sometimes I can send data but not its not regularly.
When I try the different server, I can send datas correctly.
Can you help me?
