I recently received a couple of new SFF R410M to use in my project. However the software which I had previously written does not longer work. The only difference between the old boards which I have and the new ones is the firmware version (L0.0.00.00.05.08,A.02.04 on the new boards and an older version on my existing ones) and the GNSS module (M8M on the existing ones and 8M on the new ones).
The first problem I encountered was when I tried to connect to the NB-IoT network. Using the R4X library it straight up refuses to connect using the same codebase as I previously have proven working. The AT command exchange fails with an “Operation not supported” after a number of timeouts. I got this part working by changing my MNO profile parameter from SWD_DEFAULT to SIM_ICCID which connected to the network. However, I am still unable to send messages and keep an active connection to the network after failing to send a message. Reconnecting after failing also doesn’t work.
This is really frustrating since I finally had gotten my application to run smoothly and handle disconnects and reconnects and keep it running for long periods of time. Is there anything new needed to change with the latest firmware? I’m using version 2.0.2 of the R4X library.
I really need some guidelines since I’m currently very confused as to why nothing is working.
