i use sdk14.2 52832 as central , have bas service and myself service it have pair process , there are one change question. When I first burned the program, the bas service cccd was enabled and the power was read, but 0% of the read power and the power did not receive a notify after the power was changed, everything was normal after another connection or reset, I guess it is possible It was caused by the first pairing, but the specific question was not known. This was the only strange problem after the first burning process.
