- Mon Jan 08, 2018 11:54 am #72970 the problem is clear:

client.publish();

awaits two (pointers to) character arrays as arguments (as the errormessage clearly states), but you tried to pass one integer (buttonPushCounter) and I foolishly assumed it might also take string.

so maybe sth like

Code: Select allmsg = itoa(buttonPushCounter,msg,10)
client.publish("OsoyooDataF",msg);

may actually work ...

- Mon Jan 08, 2018 7:10 pm #72982 thanks for the advice, but it seems like it's conflicting with an assignment at the beginning of the sketch...

char msg[50];

how can we reconcile this?


Arduino: 1.8.2 (Windows 7), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, 115200, 4M (3M SPIFFS)"

C:\Users\GADAWE\Documents\Arduino\node_ct_rgb_box\node_ct_rgb_box.ino: In function 'void loop()':

node_ct_rgb_box:136: error: incompatible types in assignment of 'char*' to 'char [50]'

msg = itoa(buttonPushCounter,msg,10);

exit status 1
incompatible types in assignment of 'char*' to 'char [50]'

This report would have more information with

option enabled in File -> Preferences.

- Tue Jan 09, 2018 3:42 am #72993 The assignment is not needed.

Code: Select allitoa(buttonPushCounter,msg,10)
client.publish("OsoyooDataF",msg);

- Tue Jan 09, 2018 6:04 pm #73024 works like a charm!

so much to learn about coding.... my have some follow up Qs to clean up and stabalize the experiment, but otherwise it's working!!!

thanks again!
