Hi all,
I am looking for some help on where to identify a problem that cropped up recently. I'm relatively new to the softdevice concept, though it seems straightforward...
Hey everyone,
I'm developing an application using the PCA10001 board. After a while my app crashes. I think this is due to un-freed memory regions. When writing similar...
Hi every one,
I work on application that read continuous analog signal with 500 sample/second and send it from nRF51822 board (1) to nRF51822 board (2) and read this value...

Hi,
I need to send an audio signal through BLE connection of nRF51822 module, this signal need to quantized and sampled at rate of minimum 8000 sample/second by ADC, i...
I would like a working example of a simple application that uses soft_device (either S110 or S120) plus UART debugging.
I have read many posts in this forum about this topic...
Hi folks,
do you supply a BT Test-SW to set a module with your NRF51822 in different test modes like continuous FH etc. or to change the device to low, mid, high channel...
Hi,
I want to establish a peer-to-peer communication network between 2 nRF51422, such that both the nRF51422 can Transmit as well as Receive data. Is it possible to achieve...
hi,
as we know, the device need to being linked in 1.28s if Advertising types is BLE_GAP_ADV_TYPE_ADV_DIRECT_IND ,but my host can't link device in 1.28s,so i want to link...
Hi,

Hi all!
I want to allow only 1 device to bond at a time. If another device bonding, I want to delete the previously bonded one.
I tried to use dm_device_delete_all() in...
Hi all,
I'm trying to get TWI working on the nRF51 DK but it's not working.
I used the twi_hw_master_sd.c file so softdevice use should not be a problem.
When I debug...
I am using internal ADC to sample 2 (sometimes 3) channels on about 333Hz frequency.
What I do is:
set channel 1 as input (always two-thirds prescaling, VBG reference...
