I have the UART to Ble central code running on a CY5677 dongle along with the UART to Ble peripheral code on a CY8C4248LQI-BL583.
I have a 2 CoolTerm windows on my PC, one connected to the CY5677 dongle and the other connected to the CY8C4248LQI-BL583. module.
When I type in the dongle window I see the characters in the module window , and vice versa.
When I uncomment
in the peripheral code main.h and rebuild, I only see traffic in the dongle to module direction.
I cannot see any traffic in the module to dongle (peripheral to central) direction.
Does any body know why ?
