I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
I consider to use a 32k MEMS oscillator instead of a usual 32k quartz crystal with a nRF51822 (WLCS). 32k MEMS oscillator's package is quite small 1.55 x 0.85 mm, there's...
I am developing on a custom board using nrf51822 with pure gcc. The blinky makefile worked fine. Before going to ble_hrs makefile, I want to load the blinky_example with softdevice...

Hi,
I'd like to learn about the app compatibility for the new OTA DFU that ships with the new SDK 6.0.0 and S110 7.0.0. I am using a nRF51822 board and I've observed that...
Hi!
I was trying to program bootloader provided with nRF51822-DK using nRFgo studio but I receive error like attached:
I was also trying to follow this guide:

I want to add an external PA to the NRF51422. My understanding of 15.247 is that you can transmit up to 30dBm if you use spread spectrum. Does the NRF51422 use DSSS for Bluetooth...
When is the most appropriate time to set the transmit power while using the S120 softdevice? I want to set it once at power up. Most examples that use the S110 SD set the...
