"The Bootloader/DFU with SoftDevice update example shows how a SoftDevice, bootloader, and pplication (sic) can be updated on aN (sic) nRF51822 chip"
The typo "pplication" is repeated throughout.
But my main query is that S310 is the ANT+BLE SoftDevice, but nRF51822 is the BLE-only chip - so should it say nRF51422 ?
Also, in the Introduction: developer.nordicsemi.com/.../a00051.html
"Current SoftDevice must be v.7.0.0 or later"
But there is no such version for S310 - the highest is v2.0.1
Is that supposed to be the SDK version - rather than the SoftDevice version?
