I found missing links to "LowPower" section in the online Reference Manual: https://dev.bouffalolab.com/media/doc/702/open/reference_manual/en/html/index.html
But "LowPower" section exists: https://dev.bouffalolab.com/media/doc/702/open/reference_manual/en/html/content/LowPower.html
Eventually I was able to download the documentation PDF files from: https://dev.bouffalolab.com/document
A PDF file of Reference Manual 1.2 without "LowPower" section too.
Will you publish a description of RF registers in the BL70x reference manual?
Delicates No, its private.
