Hi everyone,

I have started my first IoT project in the last few days. Based on arduino and the DEV board ESP-12S-A9-A9G-GPRS-Node-v1.0.
I would like to share my source code to discuss the following problems.

  1. The A9G module does not start at every startup. Any Idea how I can ensure that the A9G Modul starts and if not to restart the System?
  2. After about 1.5 hours to 2 hours, the GPS stop working. Any Idea how I can fix this bug?
  3. Is there an elegant solution how to select the WIFI, enter the password and then save it on the ESP for connecting?
  4. Last but not least, some Idea to optimize the code?

I hope you can help me to fix point 1 an 2 and have some good ideas for point 3.

chesterrush, conseguiu fazer funcionar com o projeto com a placa ESP-12S-A9-A9G-GPRS-Node-v1.0. A biblioteca TinyGPS ++ deu certo nessa placa? estou num projeto parecido e precisava dessas informações. obrigado

Mas a biblioteca funciona nessa placa ESP-12S-A9-A9G-GPRS-Node-v1.0 ?? Estou fazendo alguns teste e não funciona. Para funcionar (retornar a latitude e longitude) utilizei os comandos AT
