DHCP failed

TorbenFuglsang · September 7, 2016, 12:52pm

Hardware & SW:
Arduino UNO, wifi shield CC3000, Arduino for MAC version 1.6.11

Problem:
Had a Blynk project running for sometime, but suddenly the Arduino went offline.

I updated the blynk lib to version 0.3.8
IOS version 2.5.4
Now I get this error: DHCP failed

If I use blynk lib. version 0.3.6 I actually get the IP and DHCP, but then i get this message:
Looking for blynk-cloud.com

please help:-)

I tested my project again last night, and now it works with lib. version 0.3.6
It still dosen’t work with the new lib. 0.3.8 (iget the DHCP error)?

Very strange, i think there are no changes.
Do you have an SD card inserted in the slot?

I have the same problem with 0.3.8.

I recompiled the sketch with the 0.3.7 and 0.3.6 libraries and the sketch works again.

I therefore can only be because of a change between the 0.3.7 and 0.3.8 libraries.

I have tried the sketch with and without a SD card inserted on the CC3000 WiFi shield and it makes no difference.

For CC3000, we will try to fix it. For Ethernet, the problem shouln’t happen…

@rhoude57, @TorbenFuglsang, @tariktumanbay
Please try latest master branch

rhoude57 · September 13, 2016, 11:36pm

The fix works for me!

Great many thanks,
Ronald

Ethernet is a different story, need to check this.
Meanwhile, can you post your full sketch code?

tariktumanbay · September 14, 2016, 4:44pm

i m write auth code normalyy . this skecth in delete

vshymanskyy · September 14, 2016, 9:50pm

Please check latest example, it should include more code (disabling SD card): https://github.com/blynkkk/blynk-library/blob/master/examples/Boards_Ethernet/Arduino_Ethernet/Arduino_Ethernet.ino
