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,

It seems that in SDK9 the APP_BUTTON_INIT() macro has disappeared, and with it the extra argument that determines whether the scheduler is used or not.
However, the documentation...
Hi,
I want to develop one FOB key which will be in TX mode only to transmit a key continuously or at specified interval at ultra low power mode and powered by CR2032 coin...
I'm having really terrible RF performance with a PCB I've designed using a nRF51822 QFAC, Johanson 2450BM14E0003 balun, and a PCB IFA (from TI DN0007: www.ti.com/.../swru120b...
I would like to create a large “virtual” read only characteristic that does not fully exist in memory. I understand that large characteristics are transferred in chunks of...
I am trying to enable a critical section in handler. I need to update a sensitive global variable when a button event occurs, and the fact to enable/disable the interrupt...
I have nrf51822 and I use latest SD130. I scan nearby ble devices. In my case they are iPhones. When one device is in rage then I connect to it and start scan again and keep...
Hello to everyone!
So, now I try to enable a DFU for nrf51822 (S110 7.3.0)and have some problems with it.
I can't find a good example project including DFU, all that I...
I've created a simple test to demonstrate pstorage store/load for 64 pages of 1024 bytes each. To allow 64 flash pages I set PSTORAGE_MAX_APPLICATIONS to 64. Each page stores...
