print doesn't write full buffer #9
Description
In SparkFunESP8266WiFi.cpp, in function:
int16_t ESP8266Class::tcpSend(uint8_t linkID, const uint8_t *buf, size_t size),
print((const char *)buf) (line 526)
ignores the size parameter that was passed to tcpSend, and stops sending at the null byte (treating it as a string).
Because of this, I couldn't transmit the full message when I had null bytes in my message (I was sending structures & serialized data, not just strings, so it had some zero bytes)
to fix this, I replaced
print((const char *)buf)
with
Print::write((const char *)buf, size). (prepended namespace to avoid conflicts with ESP8266Class::write)
This is a somewhat minor fix, though.
//
On a side note, ESP8266Client::connected() seems to return false even when connection is established. That is, when I run:
if (!client.connected())
res = client.connect(ip,port),
it outputs 2 (already connected) even though it just indicated that the client was not connected.
Can you double check on this? It seems that either ESP8266Client::connected() or ESP8266Class::status() is doing something strange since ESP8266Class::status() never really returns ESP8266_STATUS_CONNECTED (which would make more sense if status() returned _status.stat instead of 0/1).
