What problem - the reset problem, or the other problem(s) ?

This is why it helps to keep to one question per thread!!

Hi,

What are you using as a power supply? Have you switching to a proper bench top power supply and see if the problem persist?

This is confusing!

[quote userid="9598" url="~/f/nordic-q-a/50060/nrf-52810-reset-with-pa/199950"]The device reset because of power supply[/quote][quote userid="9598" url="~/f/nordic-q-a/50060/nrf-52810-reset-with-pa/199952"]It caused reset due to power supply[/quote][quote userid="9598" url="~/f/nordic-q-a/50060/nrf-52810-reset-with-pa/199979"]The device didn't reset[/quote]

So did it reset, or didn't it?

And was that due to the PA / power supply, or wasn't it?

If you're now onto a different problem, then please verify the answer for this thread, and start a new thread for the new question.

Have you checked your power supply lines?

Check that the PA is not causing the voltage to "sag" when it transmits ...

You will need an oscilloscope - a meter is unlikely to see this.

Hi,

Have you tried using the debugger in SES to debug your application? Does it reset immediately after pa_lna_init() is called or sometime after the function has returned? Have you tried reading the RESETREAS register to check the reason for reset?
