- Topic: Bluno Beetle BLE and Blynk?You Reply: I'm not having a hard time uploading the sketch. The sketch uploads fine. I'm able to do things like blink the built-in led to confirm this. I have also connected a brighter LED to D2 and confirmed I can blink that from a sketch and tied a piezo wafer to D5 and run a tone() sketch to play notes out of it successfully. The problem comes in when I try to incorporate blynk with the code. I pair the bluno to the phone, go into blink, add a BLE widget and it won't connect. Thus the controls from blynk won't work for anything on the beetle.
I tried using regular bluetooth as well, and it will connect from blynk but then doesn't seem to control anything - not even directly turning on D2 with my LED on it. - You Reply: I was eventually able to get the bootloader to upload and I'm now able to get sketches to upload again via the serial port. I soldered some thin wires to the icsp1 connections and was using them with an ArduinoISP. However, when connecting MOSI<->MOSI and MISO<->MISO as labelled in the docs was when I was having trouble. When I tried flipping them around, it worked. I'm not sure if the docs are incorrect or not (they also showed the ICSP1 on the left rather than the right side so it may be for another device)
