VDC= 3.30V
module is taking 0.42A .
it works normally, but when i restart it, sometimes it restarted normally, sometimes didnot. only sends mac address to the uart and takes nothing from uart (when i enter ascii commands, uart data transfer led do not blink). which means that module is not responding normally.
anyone facing this problem??..
waiting for reply…
At 420mA it’s drawing 10 times the current it should while in Idle mode. Is it getting hot? Suggest you recheck your connections.
hey sorry…it is 0.042A , i was wrong. module is drawing good current. the problem is same. it works normally, but when i execute "reboot " command. module shuts down, all leds turns off except power led. uart terminal only shows wifly mac address appearing again and again… no command gets into the module. i am a software freak, these hardware issues driving me nuts brother…
After a “reboot” the module goes into “data” mode. To send it commands you must put it into “command” mode by sending it 3 dollar signs($$$) - no carriage return afterwards. There must be no characters sent for 250mS before or after the $$$. The module should reply with “CMD”.
yes it is completly understood that after reboot module goes in data mode. by “command” in previous post, i meant “$$$” . module shows no response of “$$$”. but when i restart the module by unpowering it and agian giving it 3.30V supply. module starts working normally. reboot is shutting it down , nothing appears after reboot, even mac address. which appears repeatdly when we are in data mode.
Version 2.21 is about 2-1/2 years old - you may want to update the module to the latest firmware. Don’t know if that’s your problem, but it certainly can’t hurt.
