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...

Hello,
I'm designing a new design and planning to use WLCSP version of nRF52832.
I have few questions about this since all reference designs are made with QFN48 version...
Hi every one,
I use the nRF51822 to read temperature from sensor and send it through UART, i follow the SDK examples and just change connection interval to 0.5 sec and...
Hi I am trying to get my 128x32 oled device working with my nrf52 development kit board. Using PCA10040. Does anyone have or know of any example code that can get it up and...
Hello,
I am writing some data to flash, but when it runs to storage_clear, I get the return code---0x10. It seems clear failed. And I tried storage_update, and it failed...
Hi, I'm working on a project, I want nRF51822 can get notification when android phone got a call or email, just like ANCS work with iPhone.
I tried ble_app_alert_notification...
Hello,
Apologies as I'm very new to C and I may be missing something obvious. I have an actual ble Heart Rate device which I wish to connect to my pca10028 (nrf51422_xxAC...
I am try to porting nRF51822 Beacon v1.0.1 F/W for PCA20006 to PCA10001.
I could change GPIO port setting for button and LED.
Now normal beacon mode work fine and success...
We appear to have discovered today that if you do this sequence
sd_power_gpregret_clr(0xFF);
sd_power_gpregret_set(0xA0);
sd_power_gpregret_set(0x0B);
GPREGRET will...
I'm trying to understand the general structure of .h files.
nrf.h contains an #ifdef for NRF52.
I cannot find a #define NRF52 anywhere.
Any help appreciated.
Thanks...
We have our nrf52 working well with our iOS app - almost everything we need is in place. One last item (haha) we've been struggling with is to get the nrf52 to advertise our...
Hi,
I'm connecting to a proximity sensor, IQS263 over TWI interface and having some weird problems.
I'm using the same code I used to connect with the Invensense MPU...
Hi.
We are trying to get nrf52 to work with 1.8v spi master. We are using level sifter with it. However when we connect the nrf52 to level sifter to spi output, the whole...
i am working with nrf24l01 module with PA LNA circuitry for longer distance transmission.When i bought the module i received an antenna along with it which is an SMA antenna...
