Merging spi and ble_app_att_mtu_throughput

[Ste_]

Hi, 

I'm struggling to use ble_app_att_mtu_throughput and spi. Some help? 

When I merge the two codes the main code (ble_app_att_mtu_throughput) doesn't work.

Thanks for your help

Hi,

Does the merged code build without any errors?

Jared

yes

[Jared]

Yes, but on what device are you trying to run this code on?

Sorry, I tought I mentioned it. I run the code on nRF52832

[Jared]

Hi,

How are you merging the python code with the ble_app_att_mtu_throughput sample that is written in C?

regards

Jared

I compiled it on the SPI Driver and connect it via wires on the dedicated pins (CS, MISO, MOSI, SCK). Is it wrong? It is the crucial part where I have problems

To be clear, I schematize my idea

[Jared]

Hi,

Thanks for the nice explanation, it cleared up my confusion.

You mentioned that you're not seeing log output from any of the nRF52832 devices.

1. If you only connect the client side, do you see any log output?
2. Can you share the projects that is running on server and client side?

Yes, I see the classic log output of ble_app_att_mtu_throughput

Yes, here the folder:

4885.ble_app_att_mtu_throughput.zip

I mean:

NRF_LOG_INFO("ATT MTU example started.");
NRF_LOG_INFO("Press button 3 on the board connected to the PC.");
NRF_LOG_INFO("Press button 4 on other board.");

And next the other parts of the code

[Jared]

Hi,

The project you shared doesn't contain any source file?

Ste_ said:

So you only see the log output if you only connect the client side?

Because earlier you wrote this:

Ste_ said:

When I run just ble_app_att_mtu_throughput and I open the PuTTY terminals, I see "this board act as responder" and "this board act as tester.

This doesn't happen when I add spi code. I open the two terminals and nothing happen, neither if I push the reset button on the nRF52832 boards

So please clarify, when you see log output, what log output you see, and from what device,

This is what I see on responder and on tester terminal if I try to integrate my code with SPI code.

And this is what I see if I run just the code ble_app_att_mtu_throughput:

Then, If I comment the SPI part of the code, it runs perfectly. But I need the SPI part.

Not if I integrate the SPI code

Sorry, is it right now?
