  • Hi, I am trying to implement the RN-52 into a project. For the PWR_EN pin, I get that it needs to pulled to 3.3V to be turned on, but is it not supposed to turn off when pulled down to GND? It's the weirdest device I have ever seen where the only way to shut it down momentarily is to remove power, not even through an embedded system. I have tried implementing several ways where a microcontroller can remove power, but to no avail. Is it just my unit that might be defective, or is that just the way it works?

    Thank you!

  • I figured it out - turns out the headers were not making contact with some of the breakout points (most likely the transmit/receive). I used a wire directly through the holes to the breadboard and it began working. Thank you, however!

  • Hello, I have followed the guide exactly as stated and have gotten to the point when the device can be discovered. But when I attempt to drive GPIO9 to ground, it does not enter command mode. I even placed the wire directly to the output pin on the module (in case the PCB was malfunctioning), to no avail. I checked to ensure the UART was working by looping it to itself, which it was. I even tried resetting it by driving GPIO4 in the sequence for resetting, which did nothing to the device. The device connects and outputs sound, but it simply will not go into command mode. Any suggestions?

  • Hi, I wanted to know if this programmer would work Atmel Studio.

No public wish lists :(
