Hi all ...
My product uses multiple BLE peripherals (Simblee by RF Digital) communicating with a common BLE central to time events detected via sensors on the different...
Hi,
The situation:
I was able to successfully receive known packets from a device running gzp_device_dynamic_pairing, from, the host running the gzp_host_dynamic_pairing...
So the nRF51822 has one 32 bit, two 16 bit timers and two Real Time Counters.
What is the difference in a timer and counter? The timer API seems to hard link RTC1...
Hi,

Hello,
I've got a problem with my nRF51 DK. When I attach it to the USB port the drive doesn't appear on Windows explorer and green diode doesn't flash too.
I've been...
By design, the TI LP55231 LED driver IC will fail the TWI write of the reset register (0x3D). It's necessary to reset the IC in an edge use case. I'm using the nRF51822 HW...
Hi,
I want to write a characteristic, the value size is fixed, for example the size is 4 bytes. When I try to wirte 6 bytes from the client, the first 4 bytes is writed succesfully...
Hi all,
I have the nRF52 DK programming consistently without any trouble both on Kiel and using the nRFgo Studio.
My problems arise when I connect a 3rd party module...
Hi,

Hi,
I have implemented a custom application(Lets name that file app.hex) which works and sends the data to phone via BLE on my nrf51822 DK. I am using the s110 v8 softdevice...
Due to some constraints in the manufacturing process of my product, there is substantial mechanical variation in the BLE antenna. I can constrain this variation to a degree...
Hi,
I am trying to program MDBT40 with Jlink and having some problems.
Here is the scenario:
I have two versions of the MDBT40. One that I took off a BLE NANO (RedBear...
