BG770A-GL - Long GNSS activation timeout?

Hello Support,

While testing GNSS on a BG770A-GL with the latest FW, I found that the module needs more time to reply to AT+QGPS? Manual states 300 msec, in practice I found 5 seconds?
(The same driver on the BG600L-M3 gets the reply within the 300 msec).

Thanks for your help,
Jo
