A couple general questions:
Is there a way to tell how much longer my battery will last depending on the voltage? I see that
RUI_RETURN_STATUS rui_device_get_battery_level(float *voltage); returns the voltage, but is there a way to map voltage to hours or minutes of battery life left?
I want to send data via a POST request to a url. I have most of the AT commands working, but I am wondering which functions I should use to send that data. I see:
void at_parse(char *cmd) //Im guessing that I would just send my commands here?
RUI_RETURN_STATUS rui_cellular_send(uint8_t *data);
RUI_RETURN_STATUS rui_cellular_response(uint8_t *response, uint32_t len, uint32_t timeout);
Any help would be appreciated as I am still learning
