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 am looking at using an nRF51 in a BLE product (industrial applications).
One of the things that I have to sort of prove is that it will be a better choice than something...
Hi, everyone. I would like to be notified about the brown-out on my device. I know about POF peripheral, but lowest possible threshold is NRF_POWER_THRESHOLD_V21 (which is...
First off, forgive me for being a newbie at ARM programming in general. In AVR this was straight forward.
I have a circuit connected like this to the ADC (P0.01 = AnalogInput2...
Hi,
I would like to transfer real time ecg data from a 3-channel adc (250 Hz per channel, 16 bits ) using nRF51822 to an android device. I would like to know if this is possible...
We are looking at using the Gazell protocol for a project. There isn't much information out there except for the "Gazell Link Layer User's Guide"

Hi,
I've been working with a two LPC1768 boards with connections to Addicore nRF24L01+ boards.
I have not been able to successfully receive an ack on the PTX board although...
Hello
What is a typical current draw when using a PORT GPIOTE interrupt? I seem to be drawing approximately 200uA with a port event enabled. Is this normal?
I'm using...

Hi,
I am trying to bring up custom board with 51822 CFAC-A0.
And I am continuously getting the following error as soon as the code does advertising_start().

This comment for this line of code in twi_sw_master.c is misleading:

Hello all
I'm new to Nordic products and the Keil compiler and in order to fast-track my development I have two computers, home and work, running Keil MDK-ARM (lite) with...
As said on the topic "GAP Address types", the random static address can be changed when system boots up. I can't find any content about how to make it. Could anyone offer...
