hi,I am trying to transmit at maximum power using S2-LP. I set the configuration registers using S2-LP DK Application tool version 1.3.4. I set output power as 14dBm, check the MAX power box, choose HPM mode (in PM mode section), set 1600mV SMPS volt...

I have created a project as in the video (https://www.youtube.com/watch?v=PalTKoMf_Xo&t=276s), however in my case there is an extra tab as "Platform Settings" in Middlewares->LWIP and it gives warning. After that, I couldn't take an IP address from m...

I designed a pcb with STM32F411RE and a couple of sensors. Before, and after mounting components on the PCB, I checked the Vcc and GND pins for short circuit and I did not see any problem. I am using SWD programming and I connected my ST-Link V2 to m...

Friends today I completed the board and it works good finally. I did not used any flux and did not mount LEDs and changed the programmer ST-Link. Thank you all again for your precious contribution. 

Probably I solved the problem finally. I removed the LEDs and did not use flux while soldering the STM32F411 and changed the ST-Link. As a result, the board is working fine, however I did not mount all of the components. For now, I mounted STM32F411,...

Let me explain my last experiments on the PCB. For a second PCB I just mounted STM32F411RE, C5(Vcap), R9, C10, LED2, R11 and reset button. I did not solder any sensor, any voltage regulator etc. on second PCB. I used the power lines from ST-Link. I s...

After a couple of hours later, resistance between Vcc and GND increased to kohms. After that I connected the bord to PC via ST Link V2 debugger and loaded the led blink program, 1-2 minutes later connection was lost and I observed that Vcc and GND wa...

In second experiment, I mounted only STM32F411RE, reset pin configuration and Vcap on an empty PCB and same thing happened again, after a while power pins are shorted. I supplied 3.3V from ST-Link V2. In second experiment I did not use any voltage re...
