Can I break the module(nrf52832) while program the application

[Mario]

Hello,

I have a question is it possible to break the nrf52832 if I try to load the application when the UART of the module is active(TX and RX pins are 1).

The softdevice is 2.0.1 nRF52832_xxaa_s132 board pca10040 and the example that I used is based on ble_app_multirole_lesc.

Thanks in advance.

No.

Using the tools given by nordic you should not be able to break the device in any way.

I forgot to tell you that I do not use nRFgo Studio I use the J-Link.exe to program the module if I use nrf nRFgo Studio the program do not let me to program to module if UART is active. If I use a J-Link when the UART is active I can program the module but in that case the module stop advertise and stop response via uart if a reprogram the module with nRFgo studio the problem stays, so in that case is it possible to break the module.

It shouldn't be a problem. It doesn't matter whether you use JLink.exe or nRFgo Studio. The UART is not related to programming of the nRF52 at all (unless you implement a bootloader to do it, but then you would know). There are dedicated protocols and pins for programming (Serial Wire Debugging, aka SWD).

So programming with nRFgo Studio doesn't work, but program with JLink.exe does?

Do you have anything connected to the UART?
