Nordic has installed a memory write protection detector in their device to guard against invalid writes into the softdevice memory region. It is pretty cool. They call it an MWU "Memory Watch Unit". See chapter 45 of the nRF52 product specification. When you get their assert - this happens you write to their memory - you can check the MWU registers and see if indeed a memory write happened that was in their region. Unfortunately, there is no traceback capability back to the offending caller.

Found that part of the library code which has been imported was attempting to access soft device ram directly, The access seems to have not thrown an error, but when this gets called it __looks__ like a write and I get the access fault. Reworking the library has made all the difference.

What is the RAM start setting? and what address is the pointer for?

Mine works ok (59 A8 9) with SD v6.0.0 and peripheral Uart example project in SDK v15.2.0; looks like I can't help, maybe Nordic engineer will know

6.0.0 is what came with the ble app example I'm using as a "floorplan."

I tried v6.1.0, not sure about v6.0.0. Result 59 AF 9

Maybe there is an incompatible SoftDevice installed? The above works with S132 v5.1.0 on both SDK 14.2.0 and v6.1.0 on SDK 15.2.0 using nRF52832

This made no difference.

Try this:

   // Test BLE Protocol version (SoftDevice) 59 A5 9
   ble_version_t sdVersion = {0,0,0};
   ble_version_t *p_version = &sdVersion;
   // Get actual installed SoftDevice version (may be different from header file)
   sd_ble_version_get(p_version);
