Hi Simon, I worked on the given link by you,

and i checked with different dk. found that my first dk is corrupt

that's the problem

and the link is helpful for my second dk

Hi Sunil

I'm sorry, but we can't do development for you. Please follow the debug guide I linked to in my last reply and try to find what error your application returns. If you need assistance ib wgat to do next, please let me know what the error message is and I'll point you in the right direction on what to do next.

Best regards,

It doesn't seem like you've set the DEBUG define in your project's preprocessor defines so you only get information prints in the debug terminal, not actual debug info. Please check out this ticket on how to debug your application.

Best regards,

Simon

Hi Simon,

I have check

NRF_SDH_BLE_GATT_MAX_MTU_SIZE 247

and

#define MIN_CONN_INTERVAL MSEC_TO_UNITS(100, UNIT_1_25_MS)
#define MAX_CONN_INTERVAL MSEC_TO_UNITS(400, UNIT_1_25_MS)

got debug error like

I want to send at least 200 bytes of char and

Is it possible to send 100Kbytes of samples to the ble ?

I assumed you just wanted to use the custom 128bit UUID in the BLE app UART example as well, so I would recommend using the scan response here as well. If not, please check out this novelbits blog on how to maximize throughput. You should make sure the PHY is set to the 2MBPS, ATT MTU to 247 bytes, enable DLE, and increase the connection interval if possible.

Best regards,

Simon

Hi Simonr,

Thanks for the point 1 . i have use scan response.

What about point 2

Hi Sunil

1. I'm not sure that extended advertising packets are the way to go if you only want to advertise the full 128bit UUID along with the existing advertising packet. I would recommend adding the 128bit UUID in as part of your scan response packet instead and implement a scan response to your advertisements.

How to do this is described in this tutorial, and you can also check out I.E. ble_app_blinky example, where the scan response is used.

Best regards,

Simon
