5d101b8a7b Allow passing __FlashStringHelper* in addition to char* everywhere
Arduino supplies the F() macro that allows easily putting strings in
PROGMEM and marking them with a custom type. Essentially,
a __FlashStringHelper* is just the same char*, but cast to a different
type, which allows for example Serial.print() to automatically handle
both PROGMEM and normal strings.

By letting this library accept __FlashStringHelper* as well, you can
use easily use the F() macro and reduce the chance of mixing up normal
and PROGMEM pointers.

22b77ecb68 Add Adafruit_MQTT_Subscribe::datalen
This stores the number of valid bytes in lastread. Having access to this
information allows transmitting binary data as well, containing embedded
nul bytes.

b996b096b3 Fix Adafruit_MQTT:subscribe()
This method contained a loop that checked for an existing subscription,
but it only printed a debug message if so. Now, it immediately returns
true if the subscription is already registered.

When this method succesfully adds a subscription, it was documented to
return true, but the actual code did not return anything in this case,
resulting in a compiler warning. In practice, on AVR, the value of the
first argument would be returned, which likely evaluates as true, so
it is likely it actually seemed to work fine.

6879df86f6 Add Adfruit_MQTT::connectErrorString() method
This easily allows printing error messages without having to hard-code
return values in the sketch and makes the example sketches a bit more
concise.

73f5be4e5c Use const pointers for payload
The payload data is never modified by the library, so using const is
possible without any further changes. Using const allows using a string
literal, or String::c_str() as the payload.

d7a6433b81 Add Adafruit_MQTT_Client class that implements MQTT code for generic Arduino client. Add ESP8266 example using new MQTT client class. Fix bugs with using library on ESP8266 (move CC3000 to header-only class). 2015-06-08 01:48:25 -07:00
