Is there any threshold for brown-out reset, or voltage tolerance? e.g. 1.68V...
Hi.
I have received down the source of the example of experimental_ble_app_uart in my keil.
I use register.(NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;)
but, Hardfault occurs...
Hi there,
I am currently using the nRF51 DK trying to teach myself how to create a working ble application. I am currently going through the application note nAN-36_v1...
Hello!
We are using an BLE NRF51822 chip as a GATT-Server, unfortunately without any possibility to modify its software at the moment. The BLE-setup should be very similar...
I want to run the Direct Test Mode for nRF51422 on my board, I'm trying to use the nRFgo Studio.
When I'm trying to connect to the specific COM port, I get the following...

Hi,
like many others, I'm confused with Peripheral Passkey Connection.
I'm playing with the ble_app_hrs, in order to be able to setup a Connection Passkey (for the moment...
Just got the S110 SD spec, version 2.0. Very interesting.But I've recently switched from projects on the Keil MDK IDE to the mbed environment (using the nRF5-DK as test platform...
Hi All,
Has anyone mimicked the nrf8001 ACI interface over SPI on the nrf51x22 devices using S110 soft device?
I am interested in increasing throughput by using 6 packets...
Hello,
I am working on a project regarding the pairing security of two BLE devices. nRF8001 chip follows the v4.0 specifications which lacks security against passive eavesdroppers...
I require access to SDK 4.2.2 and can't find the download link on "my pages". The link must have been removed.
I only see links for SDK 5.2 onwards.
