Tool/software:
Dear Team,
I am currently working with the Ubertooth development board (based on CC2400 design) and attempting to retrieve I/Q data from the ATEST1/2 pins. Following the user manual, I have configured the registers as follows:
• ATESTMOD_PD = 0 [to disable power down]
• ATESTMOD_MODE = 0x2 [to output signals from the VGA]
Additionally, I have connected the pins to an oscilloscope.
I have also modified the Ubertooth firmware to implement the necessary register changes. While using the Ubertooth’s Rx functionality, I can successfully obtain decoded Bluetooth broadcast information from the command line. However, I still cannot observe the expected signals on the oscilloscope.
Upon powering the device, I observed a constant voltage of 0.7V on the oscilloscope, which does not correspond to either a high or low logic level.
Could you kindly advise if there are additional registers that need to be configured or any other operations I might be missing?
Thank you in advance for your assistance.
Best regards.
