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,

Hi,
I am editing my question:
I have seen some strange behaviuor I could not explain. In order to test it I have made the next test program:
I am using the application...
Hi,
I recently bought the nrf 51 development kit. Before implementing a BLE application on the board I wanted to start with a simple application of blinking a LED by pressing...
1.I have a nRF51_DK and nrf51822(waveshare core51822)
2.Keil 5.18v and all of the needed software were Installed
3.s130 1.0.0 or 2.0.0 and sdk9.0 or 10.0 were used ...
Hi Nordic Dev Zone, Ray Kampmeier here.
I'm building Direct Test Mode (DTM) into a production application that uses the 110 soft device. Unlike the provided Nordic examples...
Is there any way to integrate SoftDevice with entire project so I can get one hex from build? I am new to CrossWorks and nRF52 and I am developing BLE device. After getting...
I want to do firmware update over the air in a STM32F4xx microcontroller which is connected with nRF51822 chip via UART (TX, RX, CTS, DTR) and BOOT pins. ST microcontroller...
Hi
I can get the current time from the server using the time service characteristic. Which function should I use to set the RTC clock on the nrf 51 to the current time...
When I add a new server of my own service I got a problem.
when I set
BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&cccd_md.write_perm);
I can send data to iOS normal,but...
Sometimes I only need to send 4 bytes instead of twenty using a notification. I've noticed the init_len and max_len parameters but I'm under the impression that this will...
i am already using sdk 10. but when we have build boot-loader program. so, generate "nrf51422_xxac.hex" file. it's working for only nrf51422.. but not for nrf51822. so, how...
Is there any difference in RAM overhead with the new app_timer module on SDK 10?
I'm my application on SDK 6.1, I have 25 app_timers which run without any issue.
