Hello,
I'm working with the example ble_app_multilink_central of S120. In this example, the scan is done correctly in the three channels of advertising?
Thanks!
I have a characteristic which is a long string. I need to be able to read and write it.
Below is the function for writing to start with. Please comment on this function...
It appears version 7.0 of the SoftDevice 110 supports over the air flashing of softdevice/bootloader/application or a zip containing a combination of the three.
Trying...
Hi,
I'm trying to get SPI (master) to work (nRF51822) for communicating with a quadrature counter (LS7366R).
I've read several implementations of SPI master, such as the...

Hi,
What's the difference between a 0.9.0 pca10000 firmware and the earlier version (0.8.0)? I noticed that the throughput with 0.9.0 on the same dongle is much less than...
I'm trying to use the TWI master example with the S120 soft device. It looks like there is a known problem trying to get the S110 working with the hardware TWI. It seems the...
Hello.
I want to make flashing of devices for production faster.
So I want to write application together with bootloader via J-Link simultaneously and not via OTA DFU.

I'm able to flash ble_app_ancs to the nrf51822, and I'm able to debug it successfully. I'm also able to pair with my iPhone 5S running iOS 7.1. After the initial pairing,...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
