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...
Hi! We're preparing a medical device and are evaluating nRF5340 chip. We'd like to know when the chip and PDK will be production ready i.e. when Development Kit for nRF5340...
Hi,
One of my customers is applying LWM2M to their target application.
And they are trying to fix LOCAL PORT of LWM2M.
I heard that when end equipment is registered...
Hello
I use nrf52832 and mpu6050. I am trying to obtain values for pitch, roll, and yaw using mpu6050.
I don't know if it's because there's no magnetic sensor, but there...
Hello Everyone,
I recently started using NRF52840 dongle, I am trying to combine USB CDC ACM with Radio TX and RX examples. Individually the codes the running without any...
sd_ble_enable() returned NRF_ERROR_NO_MEM.
when I change this:
NRF_SDH_BLE_GATT_MAX_MTU_SIZE 23 to 247
NRF_SDH_BLE_GAP_DATA_LENGTH 27 to 251
here are turn...
Is there a chip with the same or even better specs then the nRF51822 but with more transmit power (at least 20 dBm)? https://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.1...
Hello,
my BLE application needs at least 5 different services to transmit different sensor data to a GATT client. I´m wondering how I can add that many UUIDs in my packet...
Hello Nordic Team,
We are currently working on a project that has nrf51822 and currently in the production stage. We are facing an issue with Bluetooth getting disconnected...
There is a bug in nrf_bootloader_wdt_init() in nrf_bootloader_wdt.c that can cause all DFUs to fail for long WDT reload values. I found this bug because I'm using a really...
Hello,
We are using nRF52832 to develop a door lock controller. As nRF52832 cannot work as NFC master, we use another chip to read M1 cards. Everything goes well, except...
I was under the impression that when the voltage was 0 in a GPIO pin, reading from that pin would return 0, and if there was any voltage going through the pin it would read...
I found a Q&A that shows 1 channel 2MHz pulse but i don't know how to generate 2 channel GPIO pulse with 2MHz frequency
(one channel is inverted pulse to another channel...
This is a bit of a weird question, but I thought maybe I could get a few useful inputs here.
I'm working on a mesh-like project where we need to facilitate communication...
