Yes and No, you can activate the GNSS (GPS, Galileo..) and ask for the GNSS info (from cold start it me take a while to get position data). And establish a connection with GSM/LTE simultaneously. (As in they can run at the same time). The AT-command to receive data can be called fast after one another, but not Simultaneously.

// GSM/LTE AT+CGATT=1 AT+CGSOCKCONT=1,"IP","YOUR ANP" AT+CSOCKSETPN=1 AT+NETOPEN AT+IPADDR AT+NETOPEN? //+NETOPEN: 1 is net open // GNSS AT+CGNSPWR=1 AT+CGNSINF

@peter777
If you find the answer please post it. I am very interested in this as well.

@thebeardedgarage Good to know!
Thanks -Terry

@navainnovation I was having similar problem and thank you so much for the solution.
Just having 1 question is that would this still work if I put the Lora to sleep mode, or even just idle mode?

@teastain2 said in T-Display S3 AMOLED fail to boot:

@teastain2
I didn't upload any firmware,only a default factory LCD demo was in the flash, but PC can recognize the JTAG port.

@teastain2 said in T-Display-S3 "alternative" power source:

No, there have been mixed results doing this and the schematic is not clear. There are stories of damage trying this.
Yes, it is intended to output 5V to power some sensors but putting 5V into it may back feed and cause a failure.
You can put 5V into the two prong battery input, though.

Thank you for your quick reply!

@jip The recommended battery is this:
Panasonic Lithium Ion 18650 3.7V, 3400Mah
You can put 5V into the two prong battery plug and the regulator will bring it down to 3.3.
The unit will still work, somewhat @ 3v.
