Bluefruit advertising not transmitting for certain packet si

by YogurtMafia on Fri Jan 14, 2022 4:02 pm

I’m building a ble mesh network using Bluefruit as a scanner and advertiser. It works fine with certain packet sizes (31 bytes always works) but other sizes simply won’t advertise. The values that will transmit seem to change based on the first packet sent. For instance if I send a 26 byte packet it will work. 27 29 bytes will work but 25 and 28 simply do not nothing. If I send 25 bytes first 25 26 28 will work but not 27 or 29. I’m honestly completely lost with this one.

Could you supply more details? The board, your code, the versions of the software, etc?

Are you scanning for the advertisements with a tool like nRFConnect (runs well on Android, especially in landscape mode) that would let you monitor all these advertisements?

I’m scanning the advertisements first with a second itsy bitsy running Bluefruit and confirmed the results using NRF connect. The packets appear with some sizes and not with others. I’m also confirmed that the first byte ( representing the packet length) was correct along with the length value for the set data command.
