ATT_MTU example received data

[jake33]

Hello,

I am using the att_mtu_max_throughput example from SDK 15. I am using an nRF52 as tester and nRF52840 DK as receiver.

I have modified the example slightly so that I can display the received data (on the nRF52840) on a PuTTY terminal. However, I am getting strange behavior that I do not understand / know how to fix. For the first little bit, it prints out exactly what I'm wanting it to do. Then, the output becomes messy, and begins dumping hex values and stating packets were dropped. How can I ensure that the data that I'm sending (I've configured it to be an array of hex values - 0x10) are correctly received? Speed is very important in my application, ideally over 500kbps.

Here's screenshots of the output: the first image shows the correct output. This is what I'm targeting. The second shows the weird behavior. Thank you in advance for the advice and help!

Hi,

If you are seeing logs being dropped, then increase the NRF_LOG_BUFSIZE parameter in sdk_config.h

Hi,

Thank you for the reply. That fixed the logs being dropped issue. However, I'm still getting the hex dumps. Do you know how I would fix this?
