nRF51822 RF test command of LETestEnd

[Daniel]

I've been tested for BT SIG however have met error which sent 0xc000 and got 0xc000. I expected to receive 0x8xxx. Command is LETestEnd. I tested with nRF51822 customer board.

I need your opinion for solving this error.

Thank you & Regards. Daniel

So you run BT SIG LE DTM according to Core specification v4.0/4.1? First step would probably be to verify that really these 16-bit words are visible physically on UART lines connecting your DUT with upper tester (e.g. by logical analyzer).

Btw. response 0xC000 is indeed valid LE_Test_Packet_Report_Event because only highest bit says it's report, all lower bits are representing packet counter in 0-32,767 range (0x0000-0x7FFF). So 0xC000 means 0x4000 aka 16,384 packets received during the test. I do agree it doesn't make sense if your test was with lower number of packets but you should definitely correct your DTM software if it doesn't just mask the 16-bit UART response with 0x8000 but assumes that the highest nibble must be 0x8 (it can be anything higher as well).
