After Power on LED30 on RS-EB-S3 and LED 50 on UC864 are goning on for approx. 2 seconds, than the leds begin to flasch for approx. 3 seconds and than they go out.

RE: Power Supply

I suppose your power supply is not sufficient. The module going to register in the network. For this it need max power just for a moment. Is there in this moment a voltage drop the module will switch off.

Is it possible to switch it on again and proceed with AT commands?
