Yes sure. Do you have any clue of why my write request packet does not shopw the value however my write command shows the value that has been written.

Hi simon,

During the initialisation the handle was getting assigned to the uart specific handles, it has been radicated by assigning the ccd handle to the custom handle as per this peripheral.

Thanks for the support though . :D

What error do you get? What function does the error come from? Are you just using the regular ble_app_uart examples unmodified? In that case, the links I posted in the last reply should be helpful for setup and testing.

Best regards,

Simon

How do you want them to communicate, you can check out the ble_app_uart and ble_app_uart_c examples to make your devices communicate over either BLE or UART. What do you mean by gets dumped?

Best regards,

Hi i want to perform simple write write without response and read o that ...
Unfortunately this code's counter part gets dumped as soon as a connection is successfull

Could you please explain this a bit more? What information do you want exactly? And do you want it in the advertising data, or would you like to send it when a connection has been made? In any case, we have examples for both, please look at some of our ble_peripheral examples to see if you can find what you're after. ble_gatts_c might be a good starting point.

Best regards,

Simon

Okay. Thanks.
Any chance you know how to print the information of available services in peripheral on central.?

Hi Dhananjay

Please make sure that you also use the same UUID BASE on both central and peripheral. I.E. the CUSTOM_SERVICE_UUID_BASE that's used in the peripheral must be the same UUID base as the one used by the central. I believe this is called LBS_UUID_BASE in the central example you're using.

Best regards,

Simon
