S110 v7.0 available this week. What do you guys think?

[John Leonard]

A big update this week for our S110 SoftDevice. Full OTA DFU for SoftDevice and Application. Also Multi-acivity concurrency for Bluetooth Smart and 2.4GHz protocols. As Developers working with our products we're interested in your thoughts?

Hi Vaio

• The overall DFU solution consists of two parts: The Master Boot Record (MBR) built into S110 v7.0.0 or later, and a bootloader in application space. The only role of the MBR is to copy a new SD image into the SD region, or to copy a bootloader image into the bootloader region. It is up to the bootloader to actually transfer new images into the nRF51 device (allowing you to design the bootloader freely depending on your application requirements, hcoiose the transport layer freely and so on).

• Please refer to chapter 3 of the nRF51822 migration white paper to see which revisions you should use with v7 of the S110: Title

The same revision that require version 2 of the PS and RM are the ones guaranteed to work with S110 v7 or later.

• The maximum size of the application when not using banked DFU is simply the total flash size, minus the size of the SoftDevice and the bootloader (S110 v7 is 84kB, bootloader is typically 8-16kB). This means that the application will be erased when you update the SD, and you will have to restore it afterwards.
