nRF52 + EVB1000 - Tx problem.

I use nRF52832 DK + EVB1000.

I test ex_02a_simple_rx.

It’s work well.

but ex_01a_simple_tx is not working. it’s mean not recieve.

I don’t understand. Why does not it work?

Hi,

So do you have two EVB1000s and 2 DKs ?

When you try the example EVB1000 to EVB1000 - they work fine?
Then you port the RX example to DK (nRF) and use an EVB1000 (STM) TX ? - this also works fine, does it?
Then you port the TX example to DK (nRF) and use an EVB1000 (STM) RX ? - this gives you issues ?
From the attached picture you get status = … F2 … this means the the unit transmitted the frame. What status event do you get on the receiving unit?

Thanks for reply.

Yes. I use two nRF52832DKs and 2 EVB1000s.

I Test

 1. 2 EVB1000s(STM) (1 TX / 1 RX)     - It's work.

 2. 1 EVB1000(STM) (TX) + 1 nRF52832 DK (RX)     - It's work.

 3. 1 EVB1000(STM) (RX) + 1 nRF52832 DK (TX)     - It doesn't work.

 4. 1 nRF52832 DK (RX) + 1 nRF52832 DK (TX)     - It doesn't work.

Recieving unit Status reg is 0x800002.

Status REG is not change.

I solved this problem.

TX preamble code isn’t equal RX preamble code.

TX preamble code set 0. but RX preamble code set 9.

The two values were different.
