What code is in the LoRa-E5 modules that you sell?
Yesterday I received some Grove-LoR-E5 modules, which respond to AT commands through the serial port at 9600 baud, as documented. I also received some LoRa-E5 modules. I have soldered one to my own PCBs. I expected the same behaviour. Instead, I get no reponse at 9600 baud. As I cycle through baud rates what I do see is the letter “C” being transmitted every 1s, at 115200 baud.I don’t know whether this is expected behaviour, or some artifact of (say) a watchdog timer reset every second, or…(what?)
Unfortunately I don’t have an oscilloscope to watch the waveforms.
What I would like to know is: is the code in the modules the same as on the Grove boards?
Any advice for what is happening is appreciated…
