Cannot read characteristic value after wr_auth success if vlen=1

[Mark P. Mendelsohn]

Attached program has 4 characteristics

1. UUID_VLEN1 - VLOC_STACK, no rd_auth or wr_auth - value can be read after written

2. UUID_VLEN2 - VLOC_USER, no rd_auth or wr_auth - value can be read after written

3. UUID_VLEN3 - VLOC_USER, no rd_auth but wr_auth - value cannot be read after written even after reply set to SUCCESS

4. UUID_FLEN1 - VLOC_USER, no rd_auth but wr_auth - value can be read after written after reply set to SUCCESS if data is copied to VLOC_USER location

#3 cannot be read no matter what is tried

When you call sd_ble_gatts_rw_authorize_reply() are you replying with the data you want the attribute to be set to? You should set update to 1, and supply a pointer to the data you want to update the attribute with.
