The bootloader in SDK 8.1.0 (at /nRF51_SDK_8.1.0 examples/dfu/bootloader) calls pstorate_register() twice. The first time as part of bootloader_init(), then on bootloader_dfu_start...
hi,
I have implemented a UART to receive network packets from another controller to send it over BLE.
UART config are: 8bits data, 9600 baud rate, no parity, HW flow...
Hello,
I am wondering wether I need to pass regulatory tests when I use the S130 Softdevice together with a 3rd party module such as the one offered by raytac ( www.raytac...
Hi,
So i don't have any experience of working with nrf ble chips, but i was given nrf52 DK and i need to make it work as an iBeacon. So i got the dev board working without...
I'm planning to implement a mesh network, where each node (ble device) also acts as a scanner, detecting BLE advertise messages. The mesh network would then forward the advertisement...
I noted on the release notes for S110 v8 (DRGN-5556, NRFFOETT-986), that enabling/disabling blue_radio_notifications() while the Stack is not idle can cause an assert. Does...
I need something in excess of 5mA output drive. Is there likely to be any problem with connecting two or more GPIO pins in parallel(providing I use OUTSET and OUTCLR to ensure...
Hi,
I have created a project with Keil 5.15
The simply blink app works. Now I want to play with softdevice.
The only problem is... no matter what I do, my hex file always...
Hi ALl

hey,
so today I updated my NRF Tools... I guess i was using an old version before.
To test our prototypes we have a test fixture where the board is programmed at the...
I'm looking to maximize the throughput using Gazelle on the nRF51.
Assuming zero retransmissions, I believe the theoretical max should be (1/TimeslotPeriod)*PayloadSize...
There is some doubt about the nRF2401L+ RF matching circuit.From the article of <<Tuning_the_nFR24xx_matching_network.pdf>> ,it says "The balun-function is done by the 180...
