An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
I'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

Hi expert,
I am developing 51822 under SDK 6.1, and we have one button and some sensors' interrupt lines as input GPIOs in our platform. In my code, after calling gpiote_init...
Hi there,
I am trying to send six 20 byte packets per connection interval. Is changing the length of charecteristic simply

I have set up a board using device_manager_central to connect with BTLE sensors. I have used a combination of the multilink example and the heart rate collector example along...
Hi,
I used nrf51822- EK board.
GATT - s110 6.2.1 softdevice
I transfer data through UART for nrf51822-EK(PCA10001).
But this time. I used nrf51822 smart beacon...
I develop with nRFgo SDK 2.3.0.10040.
Normally PRX can communicate with PTX by auto ACK, but when there are two or more PRXs with same configuration exist, once PTX sends...
Hi all,
I am trying to use for the first time my nRF51822 development kit, following the "Development Kit User Guide v1.3".
The problem is that when I open "nRFgo studio...
Do all revisions of nRF51 have the same 4kB RAM sections with separate RAM AHB slaves? The product specification clearly states that only for revision 3 chips.
Not really a question, but it took me way to long to find out about J-Link RTT (i.e. j-link Real Time Terminal for easy debug printing so I thought I would mention it for...
I need a fixed voltage reference on my circuit. Since nRF51822 has internal 1.2V voltage reference, I am just wondering if there is a way to use this reference for external...
Header for nRF51 (nrf51.h) mentions two peripheral blocks completely missing from chip documentation. Are they functioning? If so, the comment for PATCHADDR field of PU says...
Hi there,
After prototyping a device with modules and on a breadboard, I transitioned to a custom PCB with nRF24L01+, matching network from the spec sheet, and 2.45 GHz...
