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...
I've been following the custom service nAN-36 instructions and have it mostly working on my PCA10028 board, but I have two problems that I just can't figure out. I'm pretty...
I used to be able to see my development kit in nRFgo studio and flashed S110 onto the chip. Now all I see is: "No boards connected". I am still able to flash programs onto...
Hi,
We've been seeing an intermittent connectivity issue in Yosemite in discovering BLE services, namely scanForPeripheralsWithServices does not return anything. The same...
I have based my project on the SDK 6.1 ble_app_hrs. In main.c is included app_gpiote.h which I assume is for the app_button module. However in a separate class I also use...
