I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Having some trouble using the NRF52 as RX and nrf24l01+ as TX. The NRF52 receives the packet, but for some reason it always says CRCerror.
Anyone ever tried to use NRF52...
Hey Guys,
In my custom board I need to use two different I2C bus and one SPI.

Dear developers,
As we know, nrf51 has a maximum flash erase / write cycles of 20.000 times. So, in my code, I have implemented a counter that checks if max. flash write...
Dear All,
Does it worth coding a selection (scanning?) of "relatively free" radio channel to stick to?
Say, before starting our distributed application (consider a network...
