Hi
I thought: let us quickly migrate to the latest SDK.
But that seems to be harder than anticipated.
I run into a number issues when compiling with the new code:

Good afternoon,
I have developed a custom board based on nRF51822 device and SD-110-v8. For debugging I have been usign the Ulink2 tool with Keil. Now, I want to implement...
This is not working for me. My goal is to use printf() in my code. I follow the steps outlined in this link
..including calling initialise_monitor_handles(); before calling...
I was able to measure current with the test probes I have. However, I really liked the idea of test probes that were like the ones in the drawing below. I have not seen test...
I am using the PWM library in this repository for a nRF51822. I write the following code to generate a ~ 30% dutycycle 500 kHz PWM output:
#define V_CLK 5

Hello,
I am using Timer_2 with two CC registers configured, 2 PPI channels (one for each CC register in the timer), and one GPTIO_TE to make a PWM to control dimming on...
hi,
my nrf51822dk was downloaded s110 hrs demo,and it was advertising,i used a ble sniffer dongle to get the advertising data.the AdvData is "0B 09 4E 6F 72 64 69 63 5F 48...
Why is it a standard in nordic-supplied code to initialize structs with memset like so? An example would be:
ble_gatts_char_md_t char_md;
memset(&char_md, 0, sizeof(char_md...
//Edit:
So Hung Bui just told me in another question, that there is indeed a buffer of size 6 or so?
How can I decrease that to 1 (i.e. disable it) so that only the latest...
