i’m currently using an EVB_V2.2 to evaluate a BG950A-GL-TE-A_V1.3.
When powered on some bytes transmitted via COM1:
<\r><\n>RDY<\r><\n><\r><\n>+CFUN: 1<\r><\n><\r><\n>+CPIN: READY<\r><\n><\r><\n>+QUSIM: 1<\r><\n><\r><\n>+QIND: SMS DONE<\r><\n><\r><\n>APP RDY<\r><\n>
but when sending data (like ATI\n) no respone provided (literal: no character) at all.
Checked with QCOM (on windows), minicom, hterm, strace, … (linux), own code rolled for over modems, anyway: no response.
Different timings, different response delays, different speeds (device only responding at 115200 correctly), different UART configurations.
By the way, i’d probed different RS232 adapters as well.
What am i missing?
Thanx in advance,
