Hi, power dipping is the most common reason for resets. It looks like you have a good setup but just double check the connections. Do you have CH_PD connected to Vcc ether directly or via a resistor?

thanks for answering. I have checked both directly and through resistor! but I have got the same result.

Make sure you have PullUp on RES pin too ...

thanks to answer. if you mean RESET pin, i have checked it by 10k pullup and 6.8k pull up and no connection and connect directly to 3.3v but in all of them I didn't see any difference in module operation.

- Wed Oct 21, 2015 10:39 am #31926 the problem solved by using old firmware! so, I'm sure that the problem is from firmware. if you know a good and updated firmware tell me! or give me some ways to find the source of my firmware and how to develop and modify it!
may be I can release my version or develop my own firmwares !

At last this is a common problem in this version. if anyone has it try to change it to solve reset problem.

If you are using AT cmd infterface, not sure if you can change this.

Otherwise put your wireless router in B mode only.
