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,
has anyone done some good testing on the connection quality between multiple nRF51 chipsets running on the S130 SoftDevice? (Using all four connections, 3 as Central...
I'm trying to merge 'ble_app_uart' and 'twi_sensor' example.
I developed twi function in 'twi_sensor' example. I add 'ble_app_uart' example file 'nrf_drv_twi.c'
and also...

Currently i running nordic code in Arduino IDE through the library from RedbearLab : github.com/.../nRF51822-Arduino and I facing a problem in sleeping...
Hi, can anyone explain to me about this example in this link with details :
github.com/.../main.c
I'm a newbie in nordic and i found it difficult to understand this example...
I install
gcc-arm-none-eabi-4_9-2015q3-20150921-win32
make-3.81
coreutils-5.3.0
and setup the PATH in windows
then i enter CMD mode make some command to...
I am using the LFCLK RC oscillator, 8000ms calibration interval.
Is it possible to read from some register the resulting calibration value for the LFCLK RC oscillator?
Now I work on designing a product, which is implemented by sending LMP commands to a bluetooth device with nrf51822. Unfortunately, nrf51822 liberary could not provide the...
Hello,
measuring ADC signal on P0.26/AIN0/XL2 and P0.27/AIN1/XL1 doesn't work (I get constant value from the ADC not reflecting actual voltage on the pin). AIN2 - AIN7 seem...
I need to send a disconnect command from the app layer. I've seen a few other posts that say to use uint32_t sd_ble_gap_disconnect. One post had this line of code as an answer...
I am using the RBC mesh in a networking product using the nRF51422. We would like to turn the mesh on and off at selected times, say once per hour for a minute or two. I know...
Hey,
I have been trying to set up wdt for my application which services some interrupts once in a while and advertises continuously. I put the nrf to sleep using sd_app_evt_wait...
Hello,
I'm trying to read voltage signals from a sensor using internal ADC and send them OTA. For now, my codes seems to work, but the only problem with my codes is it...
I'm connecting my nrf51 with my phone and when I move far from the microcontroller (long distance) the connection is lost
what's the function witch rise this error and what...
the code of 51822 PAN 73# must be added in SDK 6.0?
/* Add workaround when starting timer2 */
