Posted on February 14, 2015 at 07:42Hi,We have a trouble with STM32F101. We used STM32F101 for far field device. It passed all EMI/EMC test for CE, then we started to field installation.After a while, server communication was lost with some devices....

Posted on February 15, 2015 at 20:09Hi,Firstly, thanks for your interests.Only a pull-up resistor at NRST, maybe it will be better with a 100nF cap. ''because NRST is not working.'' I mean: It is not restart STM32 as I want. So the external watchdog...

Posted on February 15, 2015 at 16:204K7 pull-up resistor at NRST pin.A status led is used but not blinking.Not responding to 4 UART channels (UART0, a module connection, RS232 and RS485 converter)3V3 is smooth, STM32 also work properly after re-po...
