getCmdValue

[x893]

Hi, can you say about return value from getCmdValue function (Arduino_LoRa_Gateway.ino) if strBuff not NULL ?

Thanks

[CongducPham]

If strbuff is not NULL then you will get the string in strbuf and not a long value. Ex:

Hello# -> you will get "Hello" in strbuf

23# -> you will get the 23 (long) as a return value.

As i see if (strBuff) { strcpy(strBuff, seqStr);
} else return (atol(seqStr)); }

return value undefined. gcc ignore this situation but armcc say warning - and better if no unpredicted situation. Also some warnings in sx1272 library.

for getCmdValue logically add return 0; before last }

You're right, better to return something. Thanks,
