You said that the states of your 50's LINK LED is blinking and Status LED is ON. After EZL-50L reset and boots up again, the LINK LED should be ON. And the STS LED blinks every second. If you were not confused, operation of the module seems to be abnormal. By the way, the minimum value of time for reset is 1.5 micro second acording to the manual of EZL-50's CPU. Therefore, the module must be reset, in your case. Does your MCU use interrupt for receiving data from EZL-50? If you need just reset of the module, why don't you use AT+PWP command? This command functions software reset. Have a nice day. > zinzin wrote: > ------------------------------------ > Hello, > > Thank you for your answer. When the microcontroller send the pulse for reset (200ms) the both leds status and link are off and just after status is fixed and link is blinking. But i don't receive NO CARRIER message on the serial port. There is no message. I need to reset the EZL by removing the power. My soft works correctly with a reset by removing the power. > Is there a min pulse width for the reset ? > Is there a min delay after the reset to send AT commands ? > I have a diagram but how to join it? > Thanks in advance
