I am experimenting with a pair of DA14531 TINY modules connected to a computer via a 2-wire UART and USB/UART converter on CP2104 by using CodeLess firmware image codeless_531_standalone_set_two.hex. Establishing a connection between them works as described in Section 3.3 of UM-B-140. But the probelm is that the modules drop the connection after about 3 minutes. Is it possible to fix it so that the connection will remain active indefinitely?
Two other precompiled firmware images (codeless_531_standalone.hex and codeless_531_datapump.hex) are free of this disadvantage, but I need I2C support. I recompiled the standalone_set_two project from source, but it still drops connection after 2-3 minutes. Same happens if I recompile SET ONE firmware by adding I2C feature to it. Dialog team - please advise how to fix this.
