malloc assert!

Open abhaysbharadwaj opened this issue 9 years ago • 2 comments

I have been working with this wonderful library. in my latest project i am trying to send a "RFID number" using esp8266. I am getting the error "malloc assert!" in my serial window of arduino.

The sequence of events shown in my serial monitor of arduino are as follows:

"ARDUINO: setup wifi ARDUINO: system started scandone add 0 aid 7 pm open phy2,type:2 0 0 cnip:192.168.10.108,mask:255.255.255.0,gw:192.168.10.1 CONNECTED TO WIFI NETWORK mqtt Connected Successfully null malloc assert!"

for all other programs that i have done, i have not encountered this issue. So, i can say its because of RFID that i might be getting this problem.

My question is, is this the issue with esp8266 or the library? because, i am unable to find "malloc assert!" sentence anywhere in the mqtt library.

sorry for the long question. Hope anyone can help me out! Thanks in advance..

I have the same problem when I'm doing something more with the mqtt example code. I'm trying to read sensors via I2C, an IR remote control, a motion sensor and sending the results via mqtt to FHEM and a TFT Touch Display (UTFT). When I comment out some code fragments then it works so I think, it's a timing problem. I'm using an Arduino Mega2560 R3 and IDE 1.6.12 portable on Windows x64.

I hope that helps a little. I'm giving up.

This issue was with the ESP01 module having 512Kb memory (The blue ones).. The ESP01 available in the market now have 1Mb memory (brown color modules). I am no longer facing issues with these new modules now! :)
