ADF 7241 receive issues

Hi All.

I have a setup with two ADF7241 transceivers. I have configured one to continuously transmit 4 bytes using the packet mode. I have measured that we have a signal at 2.4Gz.

Now I have another unit receiving in packet mode. It has been setup to signal an interrupt when SDF is received and when the full package is received.

However I only get a response on the SDF, but never receives anything. I have disabled auto_fcs and frame filtering.

I have tested that I am in receiving mode (and I do get the SDF interrupt... if I do not turn on the transmitter, I do not get the SDF interrupt).

I have the following setup (after reset):

EXT_CTL = 0x18

BUFFERCFG = 0x8

PKT_CFG = 0x5

IRQ1_EN0 = 0

IRQ1_EN1 = 8

IRQ2_EN0 = 0

IRQ2_EN1 = 2

IRQ_SRC0 = 0

IRQ_SRC1 = 0

Are there any obvious details I have overlooked.. or are there any documents that tells me how to setup a simple packet mode test.

Best regards

Henrik

    Reading through the manual it seems the SDF interrupt happens no matter if the receiver is set for Packet or SPORT receive, while the RX_PACKET interrupt only happens in Packet mode.

    However I have read the register 0x13E (RC_CFG) and it is 0 (packet mode). 

    I should be in packet mode.

    Help would be appreciated Slight smile
