Hello nicky1finn,I have verified that I'm not sending \r\n after the AT commands. Still, I receive nothing when I send the AT command.
I'm using the default BAUD rate (9600), but I have tried others and no result.
I have connected an LED to P1_2 and, instead of blinking as the HM-10, it is permanently lit.

How odd.. Are you able to see the Bluetooth module using something like LightBlue? I just checked the HM-10 data sheet and it looks like the LED should be attached to PIO1. It could also just be some weird issue after loading the new firmware and not issuing the renew command. As far as communicating to it over serial, just make sure RX/TX are connected properly and aren't swapped or anything. Although I implemented logic shifting circuitry, the chip seemed to run fine at 5v. If I think of anything else it could be, I'll be sure to let you know!
