Hi all：
We update SDK from 11.0.0 Version to 17.0.2, the hardware is same, but from 17.0.2 package, we run DTM in single channel mode ,data lost is 40%. DTM from 11.0.0 package is ok. Flowing screen shot is what i am using. Any one give me help:

Hi , Kaja :
I have try with DTM from SDK v16.0.0, SDK v15.3.0, SDK v14.2.0 ,SDK13.1.0, but the problem still exsit.
As the following screen shot, In single channel mode, The current cosumption is normal or not ?
I am using following schematic, is there something wrong ?
I have saw PCA10040 Demo schematic, is it working in DC/DC mode when running DTM? If running DTM in LDO mode , how to change code?
Hi,
could you try again with 11.0.0?
Are you sure that you have not included something in the code in 11.0.0 that you have not included in the other once?
For the newest DTM, from SDK 17.0.2, include the fix:
In ble_dtm.c. line 1305:
m_packet_length = (parameter && LE_UPPER_BITS_MASK) << LE_UPPER_BITS_POS;
change to :
m_packet_length = (parameter & LE_UPPER_BITS_MASK) << LE_UPPER_BITS_POS;
Your missing a matching network for the antenna, and you might have other improvements you can do in your design, but then I need to see the layout: 
But you have used the same HW for all the tests.
Could you try to do the communication the other way, change the placement if TX and RX?
Best regards,
Kaja
