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...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
My application uses a NRF52 (SD132, SDK 15.0.0), very simple circuit and needs to be extremely low current consumption. I measured the current in conditions of BLE on and...
Hi, I'm having some issues with migrating from SDK12.1 to SDK16 while discovering services.
It seems to connect to Android without much issue, but on iOS the connection...
A project is currently utilizing an NXP module to access the SD card via 4-bit SDIO. I am exploring the feasibility of integrating an nRF52840-based module, and have a few...
I am trying to use the battery example in " /ncs/zephyr/samples/boards/nrf/battery" to measure my 3V coin cell via VDD. I am using P0.14 to enable a set load on VDD before...
I'm using a nRF52840 DK (PCA10056 2.0.1 2020,14 683193023) with an adafruit FTDI serial TTL-232 USB cable (part number P70C uses the FTDI -FT232R chip inside a translucent...
i use pca20023-sr3_nrf52832_product_example demo to test, but there was an error occued , the segger rtt views displays:

Hello,
I'm in the process of developing the HW board for a nRF5340-based product. I need the customer could update the firmware using a serial port (USB or Bluetooth is...
I am testing a number of boards with a QSPI memory module with NRF52840 chip.
The QSPI driver functions all return without error even if the chip is not present. What is...
I have made PCB 32mhz crystal footprint with error. I have used other khz frequency too. Now I can't solder 32mhz crystal is it possible to code nrf52832 and control various...
Hello,
I wanted to test the long range, so changed the primary and secondary PHY to BLE_GAP_PHY_CODED from BLE_GAP_PHY_1MBPS in the advertising_init() of the peripheral...
I'm trying to debug a Zephyr application on nrf52DK. However, due to the use of multi-threading (in Zephyr) I can't use J-Link Debug Server (as I'm used to). For executing...
Hi,
Can you please answer below queries.
1. Do you support CIoT EPS attach without PDN connectivity optimization? 2. Do you support UE Usage Type (HSS and Samsung MME...
In Nordic parlance, what is event and what is interrupt? To my understanding, in ARM parlance, events are signals that can be routed to NVIC to cause interrupts.
Basically...
Hi All,
the sdk17 documentation has the sad adc included (sad because a 12-bit adc turns out to have 9 effective bits and then with +-3% error on top of all that effectively...
