Hi Stephen, The reason for compile error is array declaration syntex is changed somewhat and it is not as documeted in eclipe or bosch website. Please use these following declaration 1. at line let data: array<CayennePayload, 1 >; use as let data = new array<CayennePayload>(size = 1); 2. at line let data: array <uint8, _ > = [0xCA, 0xFE]; use as let data : array<uint8> = [0xCA, 0xFE]; This will solve the compile issue on both application files that you shared as the issue is same.
