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...
Does the count field in ble_gattc_evt_char_disc_rsp_t refer to the number of characteristics in that instance of the struct for the number of characteristics on the connected...
Hi,
I was looking at nrf52832 MCU reference design and found button connection as below
I would like to ask why R16 & R17 are used and how necessary are they? I understand...
I have Segger open with solution 'ble_app_thingee_s132_pca20020' and Project 'nrf52832_xxaa_s132'. I drop down Thingee drivers and left double click drv_humid_temp.c. An error...
Hello All,

I had been using MDK to develope the project during the past 3 years,but recently ,I have to Segger Embedded,so I moved my project...
I have created my own mesh model, based on the light switch example, and had no problems with it when using 1 client and 1 server.
But when I use 2 servers, I noticed that...
Hi,
I was wondering about the state of your roadmap of the nRF91, announced here last year ?
When do you plan a preview development kit availability for this nRF91 ? ...
Hi,
I'm planning to implement DFU for a project with buttonless BLE and I've been running into a few roadblocks along the way. My nrfutil.exe installation was missing a...
I'm working on a driver for a sensor which uses a proprietary one-wire interface. To get data out of the device, we do the following: 1) switch the pin to output 2) 1 us low...
Hello,
I am trying to see if the following design criteria, make sense for saving battery life in small BLE dongle using a coin battery like C2032. I am using nrf51822,...
This is a simplified version of the bug, hoping someone has already seen it and can point me in the right direction.
I will have time over the next 24 hours to build and...
If I use sd_app_evt_wait in a library, I get a link error: undefined reference. A workaround seems to be: don't use it in a library.
In a library (an archive, foo.a):
