the docs explicitly say CFG commands require waiting for an ACK, all others do not. The AGPS data only uses MSG commands. This is probably because the CFG commands modify flash settings, which are a lot slower than anything that just goes into RAM.
may be. I've just preferred to wait for ACK. One may use "a pause" or a natural slowness of BLE serial.

The ephemerides are only valid for about 4 hours, so an upload at midnight is probably not too useful.
