Hey all,
I am working on a product that uses eDRX mode to receive SMS messages to execute commands. Currently we have found that we don’t generally have problems sending messages to devices that are in a good cell area or are stationary, but when the unit moves into a different TAC area then eDRX is either lost or does not work, and we require a restart of the cell chip.
Additionally, I am also confused as to what a TAC area is. My unit is able to tell me what the TAC is, but it seems like it is a local network of different towers and not just one tower. Is there a good resource to locate different TAC areas?
Our device operates only on 4G LTE B13, not sure if this is relevant.
