FAQ
Hi there --
Just received my Bluno and I can see with `AT+VERSION=?` that the firmware is 1.9.7.
I've got a less recent one that is still on 1.9.6 that I would like to update.
Are you planning on releasing the 1.9.7 firmware soon?
Thanks,
Ladislas
Hi there-
There seems to be an important problem when using the bluno mega2560 with the SIM808 shield.
Basically I plugged the SIM808 shield to a standard MEGA board (not the bluno), redirecting the shield TX/RX pins to the mega Serial1 port. This way I can communicate with the arduino using the usb/serial and the arduino can talk to the SIM808 on the Serial1.
Works great with the standard MEGA board. I've defined serial commands to power up/down the 808, send AT commands, send text messages. Using the DFRobot_SIM808 code and library. All good.
Doing this with the bluno actually kills the bluno board. I can send my program to the bluno, send benign serial commands (like AT) but as soon I try to power up the 808 modem, the bluno crashes such that it is no longer seen on the USB port (it is not seen on bluetooth either). I've repeated that with two bluno MEGA boards, thinking the first one had an earlier firmware. The second time, I upgraded the firmware to 1.97 before trying anything.
Well I'm now the owner of two bricked bluno MEGA boards and I've lost time and more than 100$ on that
