nrf24 EN300440 v2.1.1 Receiver Blocking

[JK]

I have a product using the nrf24L01+ going through the new CE testing for EN300440 v2.1.1.  The lab is asking me how to setup for "receiver blocking" test according to 4.3.4 of https://www.etsi.org/deliver/etsi_en/300400_300499/300440/02.01.01_30/en_300440v020101v.pdf

Does Nordic have any suggestions on how to do this?

Hi,

This is what we have on the subject:

RF test instructions, chapter 6: http://infocenter.nordicsemi.com/pdf/nan_24-08.pdf

And also RF Performance Test Guidelines:

Good afternoon,

I have a follow-up question. I am following the test instructions that you referenced nan_24-08, and in Chapter 6, Table 15, there is a Tx payload setup. This table shows a total of 59 or 60 bytes of payload data. I am not sure I am understanding what I should define as my expected payload. Would you please help me understand this recommended packet build?

Seems like a mistake in the documentation.

Regardless, the packet should match the payload defined on the receiver. From nRFgo SDK 2.3.0.10040\source_code\lib\rf_test\rf_test.c:

  uint8_t default_payload[MAX_SIZE_PACKET] = {0xaa, 0x1b, 0x2c, 0x10, 0x81, 0x01, 0x11, 0x1a,
                                        0xfe, 0xee, 0xcd, 0x12, 0x13, 0xa9, 0x92, 0x13,
                                        0x14, 0x17, 0x7d, 0x12, 0xdf, 0xfd, 0xaa, 0xaf,
                                        0x27, 0x65, 0x41, 0x43, 0x3a, 0x2d, 0xc1, 0x55};
