Hi,
I created an Android project that scans nordic beacons and parses the data in it (such as the tx level, major. minor, UUID etc). I'm doing some low level parsing to...
I used version 3 nrf51822 along with s110 v8.0 header files for radio unblocking. when i was trying to compile there are many errors shown up because some of the soft device...
I am driving a piezo at a fixed frequency but want to provide adjustable volume by adjusting the duty cycle. I would like to adjust it by setting the duty cycle to 5 levels...
Instead of central-peripheral relation based cluster, I am planning a linear daisy chain like network model with BLE, where a series of BLE nodes will just relay the information...
I have a system fully operational using the nRF8001 communicating to both IOS and Android devices using nRFUart app from Nordic as well as a custom app using the uart tx and...
Using IAR CWARM to develop on CFAC. IAR currently doesn't have CFAC device support built in. So I am copying over CEAA config files and manually updating. I realized that...
Hi Team,
Can anyone help regarding Cable Replacement service.
Is this service is already supported in softdevices?
What are the options if not supported?
Hello! I trying to use peripheral example with s130 stack. I have some problem:
Device is advertises well. If i connect to the device via mobile application nrf Master, after...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

I need to poll a NMEA data stream and it's easiest getting a byte at a time, but it's dropping to 30ms between individual reads in this loop:
uint8_t next = 0;
uint8_t...
Hi.
I'm working with the nRF51422 devlopement kit (pca10028) and I need to mesure the highest throughput between the nRF51 DK and a smartphone. I have seen several post...
I am using the heart rate example to do a quick demo. I am sending a short string of data one byte at a time to the iphone. I decreased the HEART_RATE_MEAS_INTERVAL interval...
