Write command, Handle is missing in Wireshark

[NadSo]

Hello,

I tested the example project "custom serial chat" from Atmel and wanted to see which Handle is used to send and receive data from Smartphone to the BLE-Board (SAMD21+ATBTLC1000). For this purpose I used the Bluefruit Sniffer LE to view the data flow on wireshark and I noticed that the write command "Rcvd write command" that shows the handle is missing.

Please can you help to fix it? I saw many Examples on Youtube where the receive write command always appear. Why doesn't it appear in my case?

Here you can see how it looks like: wireshark_data_flow.png

Thank you

Hi,

This is a forum for issues related to Nordic Semiconductor products. Since your issue does not involve a Nordic IC you'll have to contact the manufacturer for your device regarding this issue.

When you in the future decide to start developing with Nordic Semiconductor products, I would recommend taking a look at the nRF52832 development kit.

Hello Sigurd, I am using a smartphone(Central) communicating with my BLE (Peripheral) the communication is unidirectional. The indication you see on the screenshot are the values sent from my smartphone to my BLE Device to light on and off the LED. This is the reason why I don't understand because normally the central should only sent write request/command. Do you know how to d/modify it programmatically so that the central wirte request sends?
