Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I have ordered and received a MOD-BT (Uext bluetooth device) to use with my Duinomite Mega from Dontronics. I run the following basic program below and it seems to work but my MOD-BT is not being discovered. I only see the LED on for a second when I plug in me MOD-BT but at no other time does the LED light up. Does the LED of the MOD-BT suppose to light up at any other time other than when being powered up?



When I run it the MOD-BT cannot be discovered by either my computer or Ipad1 which have discovered each other but not my MOD-BT. I did a google search and I found this

https://www.olimex.com/Products/Duino/Duinomite/DUINOMITE-eM EGA/resources/MOD-BT_DUINOMITE_connection_fix.pdf

The MOD_BT PCB is dated 2009 which is three years before the connection fix was discovered on september 2012 which means I need to do the connection fix.
Anyhow I have followed the connection fix several times by shorting out pin 2 and 7 on the Uext, reconfigure MOD-BT and flash the change to the MOD-BT etc. But still the MOD-BT cannot be discovered.

Anyhow I was hoping that maybe someone on this forum has some experience using a MOD-BT with a Duinomite Mega and have some tips for me.

I am thinking that maybe I received a dud MOD-BT.

Thanks in advance,

Not aware of the problem here John, it may pay to drop Olimex a support message and see what they say. Or perhaps a message on their forum.

If you get stuck in a hole, we can always organize sending you another one to try.

Cheers Don...
