RN41 Timeout - kinda'

Wireless & IoT
1

I am using a sparkfun bluetooth mate gold with an arduino pro mini. I’m just starting out so I downloaded the example ardiono sketch and I found that it is a little fussy, but i can get it to work. I can enter the command mode ($$$), exit the CM (—), etc. But when I enter “x ” the configuration starts to print on the serial monitor but stops at “ETA=0=”. I have no problem entering other commands so the 2 boards are not locked up, or something like that. This equates to 55 characters so I don’t think it’s a buffer problem (not 64 or some power of 2). Has anyone seen this?

Thanks

Found the cause, not the reason. I added a delay(500) to the “send character to serial monitor” code block so that I could use the built in LED as an indicator of transmission. Don’t know why this would prevent the complete transmission of the config data, but it does. Maybe the RN41 times out.
