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 am using a redbear Nano v2 devboard and I am having particular trouble sending my EMG sensor data via uart. Can anyone help me out with the code. PS I am using...

Hi,
We want to send our pre-production ready product for compliance testing. Selected testing laboratory told us " Conducted sampls should be set in continuous transmit...
Dear All,
so we have an embedded SoM running OpenWRT and I was wondering if I can make use of nrfutil even if not connecting a nRF52 via USB but via UART.
What I want...
So as far as I can make out, when I load a new application into the flash, the NRF52 will attempt to first load a secondary memory space and if successful, it will then replace...
Hi,
Right now i am using Blinky example in Peripheral section of SDK15 (S140). I would like to enable Coded PHY (BLE_GAP_PHY_CODED) instead of default setting (BLE_GAP_PHY_1MBPS...
Hi, I have problem with timer in nrf52810. My TIMER2 counts very slow. I declared it as NRF_DRV_TIMER_INSTANCE(2); and config struct is:

Hi ,
I can compile and use the UART example but when I try to use it in my project I get some linking errors
I have copied and past all the sdk_config.h file to my project...
I am waiting for my custom pcb based on the nrf52832 to be ready and I want to test the flashing process. Is it possible to program a nrf52 DK with another nrf52 DK using...
Hello,
I was wondering if there is some way to program a device to act like a BLE slave, which would sleep and periodically wake up to stay in receive mode for a certain...
Hello, I'm confused what the NRF51422 uses for it's digital IO reference. So for example, If I use a 3.0V coin cell battery through its DC/DC converter: 1. What voltage does...
