Connect Digimesh and HC-05 (bluetooth) : build a bridge (without Arduino)

XBee & XBee Gateway XBee - DigiMesh

Hi,

I’m trying to build a “bridge / converter” connecting in direct a DigiMesh module (XB24-DMPIT-250) and a HC-05 bluetooth module (so without using an Arduino).

PC <<>> (HC-05)–wire–(DM) <<>> remote DM

Goal is to send API frame from a bluetooth device (a PC) to a remote DigiMesh module and get the responses.

Configuration :

  • Digimesh is 3.3V powered and 5v for HC-05.
  • Tx DM connected to Rx HC-05 / Rx DM connected to Tx HC-05.
  • Both have same serial configuration (38400,N/1/N).

It works only for one direction : I can send data from the PC and see data received on remote DigiMesh module (using xbee usb explorer)

But I’m not able to get the response, i.e data send by remote DM module to the PC.

It is doable ? I forgot something ?

Thanks a lot, best regards,

Check if the DigiMesh radios are configured for 2 way communication.
