I bought a HL6/8 DevKit with modules HL7528 (LTE) and HL8518 (GSM/UMTS) and I would know if the kit supports the new SIM cards, that means the nano and micro SIMs.
Btw, I try to connect to the board to the USB1, I sent AT command for testing but I didn’t receive any answers.
Someone knows how to manage it? does eventually the board work without a SIM card?
Thanks in advance
