Hello,
I have an arduino 328 programmed and the project board deployed on site. There is some changes to be made to the arduino sketch, which is done on the host pc. My question is How do I upload the new sketch on to the project board?
1. I dont have access to carry a laptop to the site
2. I cannot disconnect the project board and get it to reflash.
3. target board does not have ethernet (it is a dumb sequencer controlling 8 relays, now needs change in sequencing)
4. one possibility is reprogram a new chip and replace it on the project board. If this is frequent then this solution is not ideal
Another example, if I had to update say 100 boards then replacing chips would not be a good idea, instead an arduino hand held diy kit to update/reprogram the target arduinos would be a ideal choice.
I looked into arduino boot cloner but I do not know if this would work, need suggestions to move forward
