I'm using the nRF51 DK (pca10028) with the S130 0.9.0-1 ALPHA release and the experimental_ble_app_s130 example from Keil 5 doesn't work out of the box. Also I'm running 7...
This is Rajesh.C working for Sienna ECAD-Bangalore, India. We are using nRF51822 BLE in our design. I would like to know how many I2C and SPI device can be connected to the...
Hi,
I just receive a nrf51822 QFAC.
I'm using SDK 7.2 with Softdevice S110 7.1.0 with gcc.
If I compile using .ld from xxaa, It works (but using 16k RAM).
The same...
Hi, We have an nRF51244 and are using a single ADC in 10bit mode with a 1.8V supply (smooth regulated from battery) wired in LDO mode. The problem is our readings are all...

currently your device supports node role....when you will come up with...
Having just seen a couple of questions relating to DMA, which I was not aware existed on the nRF51822, I did a bit of digging, and it seems there must be newer silicon versions...
Hi all,
Please can anyone explain when the device_manager_event_handler() is triggred ?
And also, what difference between on_ble_evt() and on_sys_evt() and when they are...
Hi all,
I am using nrf51822, on pca10005 board, and debuging the s120/ble_app_hrs exple. I charged s120 v2.0 in memory.
The problem that I have is when ble_stack_init()...
