Thanks for your work before I start !
I am using CAN_TrafficModifier. I have a Can Logger replaying a recorded stream from a LEAF.
I am single stepping thru the messages. All works fine, incoming message is displayed correctly once.
Out going message is monitored by a bluetooth odbii device, connected to a galaxy tab. It connects and displays data mostly correctly. However each single message transmitted on Can0 is repeated multiple times on the Tablet connected on Can0 via the bluetooth device using the ATMA command. The tab finally displays BUFFER FULL. I presume the program is re-sending the message until the next message comes along or something. I only know enough to be dangerous and so far have not been able to figure out how to prevent this. I did look at the callback apps you have I thought that it might solve my problem but I have not been able to figure out how to get it to re-transmit the message from Can0 to Can1. I am trying to implement a man in the middle to figure out communication between the LEAF Charger(OBC) and the VCM/BMS to try and set up the charger as a stand alone charger. Not sure what the RX error is but figure I can sort that out by fixing this oroble. Help appreciated. Screen shout of output on tablet attached. The other possibility is this is a problem with the dongle not clearing it's buffer ?

Bluetooth obdII "buffer full" (SOLVED)

PROBLEM SOLVED: The MA command for the ELM327 is a silent monitor and does not send the appropriate "ACK" back to the device and so it re-transmits, Turning silent mode off prior to using the Monitor All command solved my issue and the Rx error. Now on too real work. I thought it was best to leave this here as a learning opportunity, to re-read and read again the tech documents. ;)
