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...

Can anybody please tell that what are the specs for BLE l2cap layer? In BLE 4.2 core specification it describes l2cap for BR/EDR/LE but i am not able to understand that which...
Hello Nordic Community,
I need to know how to import my PCB design from Eagle to CST Studio to simulate it and I need to know if the simulation step will be useful to enhance...
Hi all, i am experimenting on the example "ble_app_beacon" on my smart beacon kit, but i have two questions about it (though they are pretty general):
When a connection...
Hi Experts，
I use TIMER_1 and PPI to driver a 'H' style bridge for our motor. Unexpected system reset will happen if I trigger the 'H' bridge PWM with ble connected. It...
Hi,
I run the code of the radio_test example in a VisualGDB project. When I start it with a debugger connected, VisualGDB informs me that a ARM semihosting system call...
Hi, is their any brief explanation for nrf5-sdk-for-eddystone project firmware newly released by nordic. I go through the project but it is very hard to understand can any...
We have an use case that we may need to support up to ,say 500 sensor nodes and it may be added or removed dynamically. And we should collect all sensor data within 3 seconds...
Hi all:
Based the descriptions in data sheet, the GPIO9 and 10 are set to NFC antenna pins by default.
And I cannot control these 2 pin correctly by configuring the pins...
I want to use NRF51822 to advertise is door close/open. No need bidirectional data sending.
Only one way from NRF sensor to mobile phone app.
Actually I have only two different...
I am using NRF52 S132, and using UART service , but my phone is getting disconnected automatically after 1 or two minutes. I have seen this question asked in Forum but that...
Hi,
Has anyone test with Nexus 5X ?
