Hi all,
I was trying to use the S130 Softdevice but the uart peripheral doesn't work properly... I am trying to send three bytes, but only one appears. Flow Control doesn...
I am using a mutex to protect a serial debug printout.
Is it safe to use sd_mutex_acquire in a blocking manner, provided it is only called from main and softdevice callbacks...
As suggested in another post , I asked to our Nordic dealer about nRF52832 chip availability.
Thay talk about 2015 december for mass production , as your direct info confirm...
When i setup DEVICE_MANAGER_MAX_BONDS in 2 and trying to connect third device the nRF 51422 (10028) is freezing and all LED's light up. Why the algorithm in "device_manager_evt_handler...
Hi
I managed to integrate the buttonless DFU example, but while testing it, I have a few difficulties.
I use Lightblue to access my services and enable notifications...
Hello There, I want to connect two slaves to my nRF51422 PCA10028. I came up with the idea of using two master communications which share MOSI AND MISO but have different...
Can the chip be updated from an ANT device to a BT Smart Central. This means it starts its life with an S210 and then gets a serial code update to an S120. Obviously with...
Hi,
I'm testing writing and reading at one of my characteristics in Master Control Panel v.3.7.1 (SoftDevice S110 v7.1.0). As shown in the following figure, firstly I've...
Reading from the FICR seems to produce some results other than what I would expect. For example, reading from offset 0x10C seems to return the flash size (instead of 0x110...
