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...
I use SDK16.

Hello. I'm trying to make a product by running nrf51822 as an observer role.
This product will only use passive scanning and will not transmit any data.
How much energy...
Hello,
I have some issues sending valid information to nRF Connect app by bluetooth using the Aduino Nano 33 BLE with nRF52840 on it. I am using Arduino IDE and the ArduinoBLE...
Hi all,
The project I am working on consists of a BLE peripheral, a BLE central and an enhanced shockburst device. I run into a problem in the code of the peripheral:...
In a project based on Softdevice S132 7.0.1 employing the Softdevice timeslot API, I noticed that the nrf_radio_signal_callback_t function passed into sd_radio_session_open...
Hello,
I am using UART_1 to receive GNSS data. For UART_1, baud rate is 115200bps. On terminal, I can see the correct data when baud rate is set to 115200bps. When the baudrate...
Hi, i am using nrf52840 development kit , four servo motor . using 15.2 sdk version
here i am controlling the angle using adc values , i am done with one servo motor . pwm...
Hi
I am modifying the scanning and advertising paremeters for coded (125kbps).
I made the following changes in advertising

Hi All,
I am using nRF52832 SOC for my development. I would like to buy a packet sniffer for my BLE development.
Can someone please suggest a suitable device for this...
Hi
In the SDK, Replay_Cache_Entries is assigned a value of 40, which means that Replay_Cache can only process 40 unicast messages. That limits the maximum number of unicast...
Hi,
