Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hi,
I based a new device design on the Thingy91 antenna and tuning circuitry and noticing that the current consumption of the two QM12038's negates the amazing power efficiency...
1.In docs I see: “This example requires one of the following SoftDevices: S112, S132, S140”. What is the reason not to support S113?
2.Is there a way to accomplish functionality...

Hi everyone,
I have come across the FPU_FFT example project for nRF52840. Just for curiosity - I'm HW-guy - I'd like to evaluate FPU's performance - to see how many instructions...
Hi,all:
since I add USBD in ESB example,when compiling and linking,I make error as nfr_queue dose not fit UNPLACE_SECTION, overflow 20 bytes. I take the line statement about...
I have a requirement to collect data over a plant, say a power plant whose size may be 3 KM by 3KM. I am planning to have a Bluetooth mesh and collect data and control equipments...
Hi,
We currently have a regular SIM, and it works well except for the inability have very low power draw when the device is in low power states. Based on our testing, we...
Hello,
I want to learn how we generate the frequency on nrf52832. I simply take a Blinky led example and on that blinking the led. i want 1MHZ frequency . so how should...
