Hi,
we bought lora e5 modules from seeeds last month. I designed a pcb and soldered the module (just the module with vdd cap and reset button with cap). I connected it using swd with stm32 cube programmer,It asked me to disable code read protection. I did that and then the module nrst pin pulled low suddenly,after that i could not connect to the module , dont know what is the problem , i tried to solder 3 more modules on new pcbs but all have the same issue of nrst pulling low. What could be the issue?

Is NRST an output? It is unfortunately not quite clair in the datasheet.
