I'm developing a LoRaWAN tracking node based on a TTGO T-Motion board based on Acsip S76G SoC. This SoC incoporates a STM32L073RZ controller, a Semtech SX1276 LoRa Modem and a Sony CXD5603 GNSS chip. To optimize power consumption I played a little bit with the initialization of the Sony chip. Unfortunately I do not have a data sheet and user manual for this chip. I asked Sony semiconductor for the documents but they told me that they don't have. I can not believe that. So is there somebody in the community, who has some documentation on the mentioned GNSS chip. Thanks a lot for your support.

I tried to get information from Sony semiconductor and from Acsip I expect some examples for initialization of CXD5603GF GNSS chip, better a data sheet and/or user manual
