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...
Hello,
i'm working with my own board with the SD V6.0 and nrf51822 chip id QFAAG0. Already works fine.
Now i switch to the new SD V8.0. The SD V8.0 is programming with...
Hi all
We use the nRF51822 with the S130 V1.0.0. Our application initializes the TIMER2 (f = 16MHz) with a EVENTS_COMPARE interrupt on the CC channel 1 to monitor some...
I have an implementation of pstorage that works very effectively in one build of software, but is dramatically slower in another. Specifically it is taking 10 minutes to actually...
Hello everyone,
i just stuck with bluetooth Range in nrf51822. I am transmitting data using bluetooth at +4dBm(which is maximum). In my experiment my nrf51 dongle is moving...
Hello, I am using the examples\ble_central\ble_app_hrs_c project from SDK_8.1.0 with s120_nrf_2.0.0 on an nRF51422_CEAAB00. This when the variable m_scan_mode set to BLE_FAST_SCAN...

Dear Developer Zone
I have searched now a lot in the Internet, mostly the say it's possible to reprogramm the Firmware of the nRF51822. I have such a chip and a JLink Debugger...
Hi everyone,
I'm working on the nrf51822 chip and using S110 stack of SDK 6.1. Everything is fine for IPhone5s. The proximity example is running on the nrf51822 device...
Hi,
What is the minimum current draw required to keep on internal DC/DC regulator in nRF51822?
In S110 SoftDevice profile, is it possible to keep on internal DC/DC regulator...
Hi,
I developed an application for nRF51822 starting from ANCS example.
All works fine but I have current scenario ... starting from a clean situation ...

i use demo ble_app_multilink_central and ble_app_multilink_peripheral ,in SDK 8.1.0,but when i use sd_ble_gap_connect (S120 to S110)return NRF_ERROR_INVALID_STATE ,
why?...
I am checking values of my PCB with an nRF51822. VDD = 3V. AVDD ~= 800mV
I was expecting a the AVDD voltage drop to be much less. What should the AVDD voltage be? What...
