  1. Hi,

    What is the OSP message to change data rate from 400kbps to 100kbps in JF2?

    It can be changed using an OSP command (MID 178, SID 2), but depends form some module details.

      Hi Micael,

      The I2C data rate can be changed with two OSP commands MID 178 SID2, MID 178 SID 66 and MID 178 SID 70, but note that the use of those messages is not recommended, because an incorrect parameter can render the JF2 inoperable. 

      To change the data rate from 400kbps to 100kbps in JF2 with an external LNA you can send the following command:

      A0 A2 00 48 B2 46 01 8C BA 80 03 FF 00 00 0B B8 00 01 77 FA 00 00 11 52 11 52 00 00 00 00 00 00 00 52 00 00 00 00 00 41 00 00 00 00 00 00 00 00 00 00 00 00 00 01 C2 00 00 00 62 00 60 00 01 01 F4 2A 00 01 02 00 00 00 00 00 00 00 09 F7 B0 B3
