Hi,
I have a board design with the ST87M01-1301 that I am trying to bring up. The ST87M01 boots and I can control the device from the ST 87Mxx OM GUI tool, no issues with any of that.
I am trying to get the GNSS working with a single antenna as shown in the data sheet and the EVKIT. The board is routed with RF_AUX (pin 33) connected to GNSS_ANT (pin 31), all per the guidelines. A passive GPS antenna is connected at the RF_ANT (pin 35)
Is there an AT command that switches the RF_AUX On/Off to connect to the GNSS_ANT pin, or is the RF_AUX o/p always available? I have not been able to find this information in any of the ST87M01 documentation.
At the moment my board is never able to get a GNSS fix and I want to be sure I have not missed a critical configuration AT command. The GUI continually outputs #GNSSFIX: 5.
Thank you in advance for any comments or guidance.
JT
