Write command and Notification in the same channel

[chinargor]

Dear Nordic Developers,

I'm trying to write some data to a slave and when the slave gets the write command sends back a notification. My problem is that I send the write command in one radio channel (for example channle 35) but I get the notification on the next radio channel (channel 3). Is it possible to get the notification on the same channel (channel 35)?

Bellow you can see the results from the wireshark.

3990 113.087487000 Master Slave ATT 34 Rcvd Write Command, Handle: 0x000e

3991 113.089248000 Slave Master LE LL 26 Empty PDU

3992 113.141960000 Master Slave LE LL 26 Empty PDU

3993 113.143982000 Slave Master ATT 34 Rcvd Handle Value Notification, Handle: 0x000b wireshark_trac_file.pcapng Lines 3990 and 3991 are using channel 35 and the other 2 lines (3992 and 3993) are using channel 3. Is it possible increase the time between the lines 3991 and 3990? Please have a look to a attached wireshark trace file.

Any advice would be highly appreciated.

Thanks, Gor

Hi Gor,

This is strange. Could you upload the sniffer trace file ? In addition a screenshot would be nice. You can edit your question to add the files in. The slave shouldn't response to the master on different channel than the channel the last packet from master comes to slave.
