Cannot find Bluefruit friend UART (using PIC32MX250F128B)

Post by peradetlic »

Hi
I have an issue when I upload the example sketches (atcommand, bleuart) to my microcontroller (PIC32MX250F128B). The uploading is done via an FTDI cable from Sparkfun (USB to Serial) to my TX/RX pins of the microcontroller. These are connected to my TX/RX pins of the Bluefruit BLE UART Friend. I got the Serial output that the Bluefruit could not have been found and I should check the wiring and switch to command mode. But I checked the wiring several times and the BLE is in cmd mode. Can you help me?

Please post a photo of your wiring between the controller and the Bluefruit friend. If you have done any soldering also show the solder points.
