Hello Jack,
4. You have disabled power saving? If not you need to use external 32 kHz to get high enough accuracy to comply with the BT Spec.
8. The reference design can be found in the product folder under Design & development -> CC2541EM Reference…
Hello Stephen,
Thank you for sending me this information. The duration that the reset pin is low fits the minimum threshold, so that component looks good. Because your clock is not running, I would recommend checking the signal on the power lines. You…
Hi Kelvin,
Unfortunately the SensorTag for CC2541 is only provided in Cadstar. The CC2541EM designs are found here: www.ti.com/.../cc2541em-rd
The 2-layer board is done in our new CAD tool Cadence/Allegro.
Best regards,

Hi,
You can see the CC2541EM schematic here www.ti.com/.../cc2541em-rd Documents
This will show you which pins on the 2541 are connected to those on the BB. From there you can configure these pins to do what you need (i.e. SD)
You can download CC2541EMK schematic from www.ti.com/.../cc2541em-rd and refer to SmartRF05EB schematic in www.ti.com/.../swru210a.pdf . What is the output of your Ultrasonic sensor? Is it an analog signal?
